The biggest feed mistake I see backyard keepers make has nothing to do with brand. It is feeding the wrong formula for the bird’s age. A laying hen, a two-week-old chick, and a broiler headed for the freezer all need very different protein and calcium, and getting that wrong is what stalls chicks or damages the kidneys of young birds put on layer feed too soon. Match the ration to the life stage, pick a sensible feed form, and most of the hard part is done.
I judged each feed below on the numbers printed on the bag tag first: crude protein, calcium, and added amino acids like methionine and lysine. After that it came down to how well the form suits the age, how much the birds waste, whether it is organic or non-GMO if that matters to you, medicated or not, and what it actually costs once you work it out per pound. Every pick links straight to Amazon.

How We Chose These Chicken Feeds
We built these picks the way an experienced flock keeper actually shops: by reading the bag before trusting the marketing. For every feed we compared the guaranteed-analysis label, the crude protein percentage, the calcium percentage, and the added methionine and lysine that drive feather growth and egg output, then checked that the numbers matched the life stage the feed is sold for. We weighed feed form and real-world waste (dusty mash left in the trough is money on the ground), organic or Non-GMO Project certification where it is claimed, and medicated versus non-medicated status so keepers can match the feed to their vaccination plan.
Beyond the label, we leaned on hands-on outcomes that flock owners can see: steady egg output, firm eggshells that do not dent, good yolk color, and clean, well-feathered birds. We also normalized every option to cost per pound across bag sizes, because a premium organic bag can still pencil out reasonably per dozen eggs while a cheap bag wasted to spillage does not. This comparison was last updated on July 11, 2026, and reflects products and formulas currently sold in the US as of 2026, verified against manufacturer specifications.
What to Look For in Chicken Feed
Feed Form
Chicken feed comes as mash (finely ground), crumble (broken pellets), pellets (compressed), and whole-grain (intact grains, often fermentable). Crumble is easiest for chicks and bantams, pellets waste the least for adult layers, mash is the most natural but dusty, and whole-grain feeds favored by organic brands preserve intact grains but let birds pick out favorites. Match the form to your birds’ age and to how much waste you can tolerate.
Protein Content
Protein drives growth and egg production. As a rule of thumb, starter runs about 18-20% (a meat-bird starter goes higher, about 22-24%), grower about 16-18%, layer about 16-19%, and dedicated meat-bird feed about 22-24% for the starter phase, stepping down to roughly 20% for finishing. All-flock rations sit around 20%. Note that popular single-bag meat-bird feeds like Nutrena Meatbird (22%) and Kalmbach Flock Maker (20%) are a start-to-finish compromise rather than a true high-protein 23-24% starter. Choose the level that fits your flock’s age and purpose rather than simply buying the highest number.
Calcium Levels
Calcium is the key differentiator between feeds. Layer feed carries roughly 3.5-4.5% calcium for strong eggshells, while starter, grower, meat-bird, and all-flock feeds are low in calcium at around 1%. Never feed high-calcium layer feed to chicks or non-laying birds, and offer free-choice oyster shell alongside low-calcium feeds when hens are laying.
Organic vs Non-GMO
Quick guide: USDA Certified Organic is a stricter, audited standard that also forbids amprolium, so organic feed is never medicated, while Non-GMO Project Verified only confirms the absence of GMO ingredients and is not the same as organic. The two certify different things, so decide which you actually want before paying the premium. See the deeper Organic vs Conventional vs Non-GMO section below for costs and picks.
Medicated vs Non-Medicated
Quick guide: medicated chick starter contains amprolium, a coccidiostat (not an antibiotic) that helps prevent coccidiosis in at-risk or unvaccinated chicks. It is unnecessary for vaccinated chicks and is never fed to laying hens, and organic keepers cannot use it. The full breakdown is in the Medicated vs Non-Medicated Feed section below.
Decoding the Guaranteed-Analysis Label
The bag tag lists crude protein (minimum), calcium (minimum and maximum), phosphorus, and often methionine and lysine as percentages, plus metabolizable energy (ME) in kcal/kg. Read protein and the amino acids together to judge quality, check that calcium matches the life stage, and use ME to gauge how energy-dense the feed is. Those numbers, not the front-of-bag photo, tell you what your birds are eating.
Chicken Nutrition Basics
The numbers on the bag stand for real nutrients. Protein supplies the building blocks for muscle, feathers, and eggs, and its quality depends heavily on two amino acids, lysine and methionine, which is why better feeds list them separately. Calcium and phosphorus work as a pair to build bone and, in hens, eggshells, so a good layer feed pushes calcium up to 3.5-4.5% while keeping phosphorus balanced. Metabolizable energy, measured in kcal/kg, fuels growth and daily activity and largely determines how efficiently a bird converts feed.
Vitamins round out the ration: vitamin A for immunity and mucous membranes, D3 to help absorb calcium (critical for shells), E as an antioxidant, and B12 for metabolism. Many modern feeds add functional extras such as probiotics and prebiotics for gut health and omega-3 sources for richer yolks. Understanding these nutrients lets you read any label and judge whether a feed truly fits your flock rather than trusting the brand alone.
Choosing the Right Feed for Each Life Stage (Poultry & Chickens)
The single most common chicken-feed mistake is feeding the wrong formula for a bird’s age. Chickens, and poultry more broadly, need different protein and calcium levels as they grow, and matching the feed to the life stage keeps them healthy and laying well.
Starter feed (0-8 weeks): Chicks need the highest protein, typically 18-20%, or up to 22-24% for meat birds, to fuel rapid early growth. Calcium is kept low because developing kidneys cannot handle the high calcium in layer feed. Choose crumbles, which are sized for small beaks. Medicated starter contains a coccidiostat (amprolium) to help prevent coccidiosis; non-medicated is the choice if your chicks are vaccinated or you prefer to avoid medication.
Grower / pullet feed (8-18 weeks): Once chicks become pullets, their growth slows and protein needs drop slightly to around 16-18%. Grower feed still keeps calcium low; this is the stage where switching to layer feed too early can cause kidney damage (urate deposits and visceral gout) in young birds. If you keep a mixed-age flock, a flock-raiser or all-flock feed at around 20% protein with calcium offered separately is the simplest, safest option.
Layer feed (18 weeks or first egg): When pullets start laying, switch to layer feed with 16-18% protein and 3.5-4.5% calcium for strong eggshells. Make the switch gradually over about a week by mixing old and new feed. Offer free-choice oyster shell so hens can top up calcium as their bodies demand.
Broiler / finisher feed: Meat birds run a high-protein curve, starting near 22-24% and stepping down toward 20% for finishing, with low calcium throughout. This supports fast, efficient weight gain over a 6-8 week grow-out.
All-flock / flock raiser: A practical alternative to juggling three bags. Feed a single ~20% protein all-flock formula to every bird and provide calcium separately so only the layers consume it. This is popular with keepers running mixed-age or mixed-species poultry flocks (chickens, ducks, turkeys, geese, guineas). Whatever the stage, transition gradually over about a week to avoid digestive upset.
Mash vs Crumble vs Pellet vs Whole-Grain
Feed form is not just texture, it changes waste, cost, and which birds eat well. Crumble is the easiest form for chicks and bantams because the small particles suit tiny beaks, and it is the default for most starter feeds. Pellets waste the least for adult layers since birds cannot pick through them, which makes the cost per usable pound the lowest of any form for a laying flock. Mash is the most natural and easily digestible texture but it is dusty, and birds can selectively eat the bits they like and leave fine powder behind.
Whole-grain and fermentable feeds, favored by organic and soy-free brands like Scratch and Peck, preserve intact grains and can be soaked or fermented for a nutrition and digestibility boost, but birds may leave the powdery fines at the bottom. Because form drives waste, it also drives real cost: a slightly pricier pellet that ends up entirely in the bird can beat a cheap mash that half ends up on the ground.
Medicated vs Non-Medicated Feed
The medication in medicated chick starter is amprolium, and it is widely misunderstood. Amprolium is a coccidiostat, a thiamine blocker that starves coccidia in the gut so a chick’s immune system can build resistance. It is not an antibiotic, and it does nothing against bacterial illness. Medicated feed makes sense when chicks face real coccidiosis pressure, for example brooding on used bedding, in warm humid conditions, or in a flock that was not vaccinated against coccidiosis.
It makes less sense when chicks were vaccinated against coccidiosis, because the medication can blunt the vaccine, and it is simply not an option for organic keepers since amprolium is not allowed under USDA Organic rules. The hard rule that never bends: medicated feed is never for laying hens. One brand-specific caution worth knowing is that Manna Pro medicated starter is labeled for chicks only, not for ducklings or turkey poults, which can be sensitive to amprolium dosing. When in doubt, a quality non-medicated starter plus clean, dry brooder management is a safe default.
Organic vs Conventional vs Non-GMO
These three labels are not interchangeable. The USDA Organic seal is a stricter, audited standard: organic feed uses certified-organic ingredients, forbids GMO crops, and never contains amprolium or synthetic medications. Non-GMO Project Verified is narrower, it confirms the ingredients are not genetically modified, but the feed can still be conventionally grown and is not organic. Conventional feed from a reputable mill is still complete and balanced nutrition; the organic and non-GMO premiums buy you process assurances, not necessarily more nutrients.
Honestly, organic costs roughly twice as much: a 50 lb bag of conventional layer might run around $15 while comparable organic runs $30 or more. Whether that is worth it depends on your goals, selling certified-organic eggs, avoiding pesticide residues, or personal preference. A distinct niche is corn-free and soy-free feed for flocks with sensitivities or keepers who avoid those crops. The strongest options here are Scratch and Peck, New Country Organics, Mile Four, Small Pet Select, and Hiland Naturals, most of which come as whole-grain or mash rather than pellets.

Detailed Product Reviews
1. Scratch and Peck Naturally Free Organic Layer - Best Overall & Best Organic
Scratch and Peck Naturally Free Organic Layer is our top pick for overall quality. It is a USDA-certified organic, soy-free and corn-free whole-grain mash built for laying hens 20 weeks and older, running 16% crude protein with added calcium (roughly 4 to 5%) for strong eggshells. A higher-protein 18% grade is also offered if your hens are especially active, free-ranging, or molting.
What sets it apart is the clean, whole-grain formulation with no soy or corn, which suits flocks with sensitivities and keepers who want to see intact ingredients rather than a uniform pellet. The mash can be soaked or fermented, which many keepers find boosts palatability and digestibility and stretches the bag a little further.
The tradeoff is dust: as with any mash, birds can leave fine powder at the bottom of the feeder, so a deeper trough or a splash of water to make a wet mash cuts waste. For health-conscious keepers who want certified-organic, allergen-friendly nutrition, it is worth the premium.
Key Features: USDA-certified organic, soy-free and corn-free, whole-grain mash, 16% protein (18% grade available), added calcium (~4-5%), fermentable
2. Nutrena NatureWise Layer Feed - Best Value & Best Probiotics
Nutrena NatureWise Layer Feed is the best-value pick for everyday laying flocks. It delivers 16-17% protein with added calcium (about 3.5-4.5%) for eggshell strength, plus essential amino acids to support steady egg production, all at a mainstream price that is easy on a monthly feed budget.
The standout feature is added probiotics, which support a healthy gut microbiome and can improve nutrient absorption. The feed comes in both crumble and pellet forms, so you can pick whichever your hens waste less of, and it is widely stocked in 40 lb bags for a low cost per pound.
This is the feed to reach for when you want reliable, balanced layer nutrition without paying an organic premium. It is a strong default for small backyard flocks and larger coops alike.
Key Features: 16-17% protein, added probiotics and amino acids, crumble or pellet, added calcium, budget-friendly, widely available
3. Manna Pro Non-Medicated Starter Crumbles - Best Starter for Chicks
Manna Pro Non-Medicated Starter Crumbles is built for chicks from hatch to about 8 weeks. It provides 18% protein to fuel rapid early growth, with low calcium (around 1%) that is safe for developing kidneys, in a fine crumble sized for small beaks.
The non-medicated formula is the right choice if your chicks were vaccinated against coccidiosis or you simply prefer to avoid amprolium. It is highly digestible and includes the vitamins and minerals chicks need for bone development and immune function. Note that Manna Pro’s medicated version is labeled for chickens only, not ducklings or poults, so read the bag if you brood mixed species.
Widely stocked in small bag sizes, it is an affordable, reliable way to raise a healthy batch of chicks without committing to a huge bag you cannot finish.
Key Features: 18% protein, non-medicated, crumble form, low calcium, for chicks 0-8 weeks, small bag sizes
4. Purina Flock Raiser - Best Grower & All-Flock
Purina Flock Raiser is the most flexible pick, a higher-protein ration for the in-between grower stage and for mixed flocks where one bag has to feed everyone. At around 20% protein it suits growing pullets from 8 to 18 weeks, meat birds, and flocks that mix chickens with ducks, turkeys, or geese.
Crucially, it is formulated without the added calcium of layer feed (roughly 1%), which makes it safe for young birds and any bird that is not actively laying. When you keep layers in the same flock, offer crushed oyster shell free-choice on the side and the hens will take what they need for strong shells.
The crumble texture suits most ages, and the recipe adds amino acids, vitamins, and minerals to support feather growth and condition. If you do not want to juggle separate starter, grower, and layer bags, this all-flock approach is the simplest way to keep a mixed-age backyard flock well fed.
Key Features: ~20% protein, low calcium (~1%), crumble form, all-flock and mixed-species use, added amino acids, supports feather growth
5. Small Pet Select Chicken Layer Feed - Best Pellet Layer
Small Pet Select Chicken Layer Feed is our pick for keepers who want the low waste of pellets with a cleaner ingredient list. It runs 18% protein, higher than many mainstream layer feeds, with added calcium for eggshell strength, and it is non-GMO, corn-free, and soy-free for flocks with sensitivities.
The pellet form is the real advantage: birds cannot pick through it, so selective eating and spillage drop and more of every pound ends up in the hen. The recipe also folds in seeds and probiotics for palatability and gut health, and it is made without cheap fillers. Its calcium sits toward the lower end of the layer range, so offering free-choice oyster shell alongside it is smart for high-output hens.
For a laying flock where you want a higher-protein, allergen-friendly ration and the tidy convenience of pellets, this is an excellent choice that competes with organic feeds on quality while staying non-GMO rather than certified organic.
Key Features: 18% protein, pellet form, added calcium, non-GMO, corn-free and soy-free, added seeds and probiotics, low waste
Best Chicken Feed by Brand
Purina is the most widely available brand, with Start & Grow for pullets, Layena and Layena+ High Protein (19%) for hens, Flock Raiser for mixed flocks, and a full Purina Organic line. It is the safe default when you want a proven feed you can buy anywhere.
Nutrena (NatureWise and the value Country Feeds line) is the best-value mainstream brand, strong on probiotics and offering everything from chick starter to a 21% Free-Range Egg Producer and a dedicated Meatbird formula. Best for keepers who want quality without an organic premium.
Kalmbach punches above its price with Flock Maker (20%, doubles as a meat-bird starter), the multi-grain Henhouse Reserve layer, and certified Kalmbach Organic options, all with added prebiotics and probiotics. Best for mixed flocks of chicks and meat birds.
Scratch and Peck is the benchmark for USDA-organic, soy-free and corn-free whole-grain feed, ideal for allergen-sensitive flocks and for keepers who like to ferment. Manna Pro is the go-to for small bag sizes and easy availability, best for first-time chick raisers.
New Country Organics and Mile Four serve the organic corn-free and soy-free niche with USA-grown grain, best for keepers who want certified-organic allergen-free rations. Hiland Naturals is Non-GMO Project Verified with soy-free options on request, tested free of pesticides and mycotoxins, best for non-GMO keepers who do not need the organic seal. Small Pet Select rounds out the field with non-GMO, corn-free and soy-free pellets and crumbles for small backyard flocks that want a cleaner label.
Quick-Grow Feed for Meat Birds and Broilers
Meat birds are a different game from layers, and feeding them like hens will stunt them. The proven approach is a stepped protein curve: start Cornish Cross and other broilers on about 23-24% protein for the first couple of weeks, then step down toward 20% for the finishing phase. High protein early builds frame and muscle, while a slightly lower, energy-dense finisher packs on weight efficiently.
The reason those numbers matter is feed conversion. Metabolizable energy and the amino acids lysine and methionine largely determine how many pounds of feed it takes to add a pound of bird, and a well-formulated meat-bird ration keeps that ratio tight across a typical 6-8 week grow-out to butcher weight. Keep calcium low throughout, meat-bird feeds are not for laying hens, and the high calcium in layer feed does broilers no favors.
The strongest dedicated picks are Nutrena NatureWise Meatbird at 22% start-to-finish and Kalmbach Flock Maker at 20%, which doubles as a meat-bird starter. Both are a single-bag compromise rather than a true 23-24% starter, so if you want to hit that higher opening protein, supplement early or choose a dedicated broiler starter. For organic grow-outs, look to New Country Organics and Kalmbach Organic meat-bird options via search.
Buying Chicken Feed Online: Large Bags and Best Price per Pound
Chicken feed sells in 10, 25, 40, and 50 lb bags, and the larger bags almost always cost less per pound, so the real skill is buying the biggest bag your flock can finish before it goes stale. Because a single laying hen eats roughly 0.25 to 0.30 lb per day (more for large breeds or in cold weather), a flock of five to six hens goes through a 50 lb bag in about four to five weeks; a smaller flock takes longer, so size down the bag to keep the feed fresh. That usually makes the 40 or 50 lb bag both the cheapest and the freshest choice for an average backyard flock.
The number that matters is cost per pound, not the sticker price. Conventional feed often runs roughly $0.30 to $0.45 per pound, while organic and soy-free feeds can be $0.60 to $0.90 per pound or more, so an organic 50 lb bag can cost double a conventional one. A pricier bag can still pencil out reasonably per egg, while a cheap bag half-wasted to dust and spillage is a false economy, which is another reason low-waste pellets can beat cheaper mash on true cost.
Where you buy matters too. Local feed stores and mills usually beat online prices once you factor in the shipping weight of a 50 lb bag, and buying direct from a regional mill can be cheapest of all for standard rations. Buying large bags online shines for specialty organic, corn-free, or non-GMO formulas your local store does not stock. Always compare on price per pound after shipping, not on the shelf tag.
Feeding Amounts and Schedule
Plan on roughly 0.25 to 0.30 lb of feed per hen per day (large breeds or cold weather can push this toward 0.33 lb), which is about 1.75 to 2 lb per week per bird. That means a 50 lb bag feeds a single hen for around 25 to 30 weeks, a flock of five for about five weeks, and a flock of ten for two to three weeks. Free-feeding from a hanging feeder works well for most backyard flocks, since hens self-regulate; just refill before it runs empty and keep the feeder off the ground to cut waste and rodents.
On cost of ownership, at conventional prices a hen eating about 8 lb a month runs roughly $2.50 to $4.00 per month in feed, or more on organic. Spread across a hen laying five or six eggs a week, that pencils out to somewhere around $1.00 to $2.00 per dozen in feed alone, before bedding, grit, and oyster shell. Free-ranging birds forage some of their own calories in the growing season, but pasture is not complete nutrition, so keep quality bagged feed available year-round to hold up egg production.
Supplements: Grit, Oyster Shell and Treats
Grit and oyster shell are constantly confused, but they do completely different jobs and are not interchangeable. Insoluble grit is small, hard stone that lodges in the gizzard and physically grinds up whole grains, seeds, and forage, so any bird eating anything other than a complete crumble or pellet needs it, chicks included in a tiny chick-grit size. Oyster shell is soluble calcium that dissolves in the hen to build eggshells, and only laying hens need it. Offer both free-choice in separate dishes so each bird takes what it needs.
Treats should stay under about 10% of the diet so they do not dilute the balanced base feed. Scratch grains are a fine cold-weather treat but they are candy, not nutrition, so keep them modest. Higher-value protein treats like dried mealworms and black soldier fly larvae are useful during molt when birds are regrowing feathers. If you see soft or thin-shelled eggs, the cause is almost always a calcium shortfall rather than the base feed, so add free-choice oyster shell before you switch brands.
Storing Feed and Keeping It Fresh
Feed quality degrades fast once the bag is open, so storage protects the money you spent. Keep feed cool, dry, and airtight in a sealed metal can or heavy-duty plastic bin that blocks moisture and keeps out rodents and wild birds, which also cuts disease risk. Most feed stays freshest used within about four to six weeks of opening, and feeds with added probiotics or freshly ground organic grains lose potency faster than heavily processed conventional pellets.
This ties directly back to bag size. A 50 lb bag is the best value per pound only if your flock finishes it in time; for a two or three hen flock, that same bag can go stale or grow mold before it is gone, and moldy feed carries a real mycotoxin risk that can sicken birds. Match bag size to how fast your flock eats, store what you buy properly, and never feed anything that smells musty or looks caked or discolored.
Frequently Asked Questions
What is the best chicken feed overall?
For most backyard flocks the best all-round pick is a complete, life-stage-matched ration from a trusted mill. Our top overall choice is Scratch and Peck Naturally Free Organic Layer, a USDA-certified organic, soy-free and corn-free mash at 16% protein with added calcium. If you want probiotics and lower cost, Nutrena NatureWise Layer is the best value, and Purina Flock Raiser is the most flexible for mixed-age flocks.
Is chicken feed the same as poultry feed?
Chicken feed is one type of poultry feed. Poultry feed is the broader term covering chickens, ducks, turkeys, geese and guineas, and each species has slightly different protein and calcium needs. A complete all-flock or Flock Raiser ration, such as Purina Flock Raiser, is formulated to feed mixed poultry together at around 20% protein with calcium offered separately, so only the laying hens top up their shells. For a single-species laying flock, a dedicated chicken layer feed is still the better match.
What is the best layer feed and what protein and calcium should it have?
A good layer feed runs 16 to 18% crude protein with roughly 3.5 to 4.5% calcium so hens can build strong eggshells. Higher-protein layer feeds around 19 to 21% suit active free-range or molting hens. Look for added methionine and lysine, plus vitamin D3 to help calcium absorption. Always start layer feed only once pullets are laying or about 18 weeks old.
What is the best grower feed for chickens?
The best grower feed for chickens is a low-calcium ration around 16 to 18% protein fed from about 8 to 18 weeks, after starter and before layer feed. Purina Flock Raiser at about 20% protein and other all-flock formulas work well here and let you feed a mixed-age flock from one bag, as long as you offer oyster shell separately for any laying hens. The key is keeping calcium low until pullets actually start laying at around 18 weeks, since high-calcium layer feed can damage young kidneys.
What is the best feed for fast growth or quick-grow meat birds?
Meat birds need a high-protein broiler ration, starting near 22 to 24% protein for the first weeks and stepping down to about 20% for finishing. Nutrena NatureWise Meatbird at 22% and Kalmbach Flock Maker at 20% are strong single-bag picks for Cornish Cross and other broilers, though they are a start-to-finish compromise rather than a true 23 to 24% starter. This high-protein, high-energy curve supports a typical 6 to 8 week grow-out to butcher weight. Meat-bird feeds keep calcium low, so they are not for laying hens.
Do I need medicated feed, and is it safe for laying hens?
Medicated chick starter contains amprolium, a coccidiostat that limits coccidia in the gut, not an antibiotic. It is useful for chicks at risk of coccidiosis and for unvaccinated birds, but is unnecessary if your chicks were vaccinated against coccidiosis. Never feed medicated feed to laying hens, and observe any label withdrawal guidance. Organic feeds are never medicated because amprolium is not allowed under USDA Organic rules.
How much calcium does layer feed need and do I still need oyster shell?
Layer feed already carries about 3.5 to 4.5% calcium, which meets most of a laying hen’s needs. It is still smart to offer crushed oyster shell free-choice on the side so individual hens can top up as their bodies demand, especially high-output layers. If you feed an all-flock or grower ration to a mixed flock, free-choice oyster shell is essential because those feeds are low in calcium.
How much does chicken feed cost per pound, and where is it cheapest to buy in bulk?
Conventional feed often runs roughly $0.30 to $0.45 per pound, while organic and soy-free feeds can be $0.60 to $0.90 per pound or more. Buy the largest bag your flock can finish in four to six weeks, since 40 and 50 lb bags almost always cost less per pound than small bags. Local feed stores and mills usually beat online prices once you factor in shipping weight, but online is the easiest way to find specialty organic or corn-free formulas. Always compare on price per pound, not sticker price.
Is it cheaper to buy chicken feed in large bags online?
Large bags almost always cost less per pound than small bags, so a 40 or 50 lb bag is usually the cheapest way to buy as long as your flock finishes it in four to six weeks. Buying those large bags online is convenient for specialty organic, corn-free or non-GMO formulas your local store does not stock, but shipping weight often makes a local feed store or mill cheaper for standard rations. Always compare on price per pound after shipping, not the sticker price.
When should I switch from starter to grower to layer feed?
Feed starter from hatch to about 8 weeks, grower or an all-flock ration from about 8 to 18 weeks, and layer feed from 18 weeks or the first egg. Switch gradually over about a week by mixing old and new feed to avoid digestive upset. Do not move birds onto high-calcium layer feed early, since it can damage young kidneys.
Do chickens need grit, and how is it different from oyster shell?
Grit and oyster shell do two different jobs. Insoluble grit is small hard stone that sits in the gizzard and grinds up whole grains, seeds and forage, so any bird eating anything other than complete crumble or pellet needs it. Oyster shell is soluble calcium that dissolves to build eggshells and is only needed by laying hens. Birds on pasture or scratch need grit; hens laying eggs need oyster shell, and many flocks need both offered separately.
Final Verdict
Scratch and Peck Naturally Free Organic Layer is our best overall and best organic pick, a clean soy-free and corn-free mash for health-conscious keepers. Nutrena NatureWise Layer is the best value with probiotics, Manna Pro Non-Medicated Starter is the best starter for chicks, Purina Flock Raiser is the most flexible all-flock and grower feed, and Small Pet Select is the best low-waste pellet layer. For meat birds, Nutrena NatureWise Meatbird at 22% is the standout quick-grow ration.
Whatever you choose, the fundamentals do not change: match the feed to your birds’ life stage, keep chicks and non-laying birds off high-calcium layer feed, and offer free-choice oyster shell and grit in separate dishes so each bird takes what it needs. Always provide clean, fresh water, since hens drink far more than they eat and dehydration stops laying fast, and store feed airtight and cool so the value you bought does not spoil before your flock finishes the bag.
Related reading: Dialing in how much and how often you feed matters as much as the brand, so start with our guide to small-pet feeding schedules and portion control. A laying flock also needs constant clean water, covered in the best small-pet water bottles and hydration gear, and seasonal swings change how much birds eat, which is why coop temperature and humidity monitoring is worth dialing in. Keeping birds healthy also means watching for early problems, covered in small-pet health monitoring and early warning signs, being ready with a small-pet first aid kit, and escape-proofing and predator security to protect the flock you are feeding.
