Feeding chickens well is simpler than it looks, but the details matter. A balanced diet supports steady growth, glossy feathers, strong eggshells, and calm behavior. When people ask what do chickens eat, the most accurate answer is a mix: a complete feed tailored to age and purpose, clean water, minerals like grit and oyster shell, and modest, well-chosen treats. This guide blends practical experience with core nutrition principles recognized by poultry extension programs and feed standards to help you build a feeding routine that is both healthy and realistic.
Why Diet Matters
A chicken’s body is always working. Chicks convert protein into new tissue, pullets prepare their reproductive tract, layers build eggs daily, and molting birds rebuild feathers. Each of these jobs requires protein, energy, vitamins, and minerals in the right ratio. Shorting one part—like calcium or methionine—can ripple into soft shells, feather pecking, or slow growth. A clear plan keeps you ahead of problems.
The Core Feed
The main feed for most flocks is a complete commercial ration. This is the primary feed because it’s formulated to meet nutrient targets consistently. Chicks thrive on starter feed around 18–20% protein. Growers do best with 16–18%. Mature layers usually sit near 16% with added calcium. Pellets reduce waste, crumbles are easy for small beaks, and mash can work if kept dry and fresh. Whether you keep a small backyard flock or a working farm flock, a complete feed is the baseline that makes everything else optional.
Reading a Label
A guaranteed analysis lists minimum protein and fat and maximum fiber and moisture. Look for a protein level matched to age and purpose, a balanced calcium-to-phosphorus ratio, and added vitamins A, D3, and E. Some starter feeds are medicated with amprolium to reduce coccidiosis risk in chicks; this is not an antibiotic and is widely used in early life stages. If you brood chicks on clean bedding and manage moisture, non-medicated starter is also common. Choose one approach and keep the brooder dry.
Water, Grit, and Calcium
Water is the most important nutrient. Chickens drink more than you think, especially in heat or while laying. Keep waterers shaded, scrubbed, and refilled. For digestion, chickens need grit—small, insoluble stones—to grind fibrous foods in the gizzard. If your flock only eats crumble or pellets, grit is less critical; add it when offering whole grains, greens, or scraps. For layers, provide oyster shell or another calcium source free-choice. Birds will regulate their intake, and this simple addition makes shells stronger without overloading non-laying flockmates.
What Do Chickens Eat Naturally?
Left to forage, chickens hunt for seeds, sprouting grasses, clover, tender leaves, insects, worms, grubs, and the occasional small amphibian. They scratch the topsoil to find larvae, pick at seed heads, and graze short greens. In wet seasons, bugs and greens dominate; in dry or cold periods, seeds and stored fat from feeds matter more. Natural foraging reduces boredom, boosts gut diversity, and translates into richer yolks, but it doesn’t always balance minerals or protein across seasons. Think of foraging as a healthful supplement to a complete ration.
What Do Chickens Eat in the Wild
The red junglefowl, the wild ancestor of domestic chickens, thrives on a varied omnivorous diet of seeds, fruits, young vegetation, and invertebrates. Climate and habitat shape availability, but the pattern is consistent: small frequent meals, constant movement, and a bias toward protein-rich invertebrates when available. This heritage explains why backyard flocks go wild for beetles and grasshoppers and why a bit of pasture time can calm a restless coop.
What Do Chickens Eat on a Farm
Farm flocks typically receive a complete feed plus pasture or yard access. Rotational grazing in mobile tractors or fenced paddocks keeps greens fresh and breaks parasite cycles. Farms often add garden seconds—kale stems, outer cabbage leaves, overripe tomatoes—alongside safe kitchen scraps. The trick is consistency. Keep feeders off the ground, store feed dry and rodent-proof, and swap wet or moldy feed immediately. On pasture, expect feed intake to dip when forage and insects are abundant, then rebound as conditions change.
Everyday Safe Treats
Treats can improve nutrition and keep birds engaged, but they should be 5–10% of total intake. Leafy greens (kale, lettuce, chard), brassicas (broccoli, cabbage), squash and pumpkin, cucumber, melon, berries, and herbs are solid choices. For protein treats, mealworms and black soldier fly larvae are favorites; scrambled eggs are excellent in moderation. Use scratch grains sparingly; they’re energy-dense but light on amino acids and micronutrients. In heat, water-rich foods like melon help with hydration. In winter, a small warm mash can lift energy without displacing complete feed.
What Can Chickens Not Eat
Avoid avocado skins and pits, raw or dried beans (especially kidney beans; lectins are dangerous unless fully cooked), green potato peels and sprouted potatoes (solanine), chocolate and caffeine, alcohol, very salty or greasy foods, and any product containing xylitol. Don’t feed moldy or spoiled feed—mycotoxins harm the liver and reduce laying. Large whole foods can be choking hazards; chop or cook dense items. If you share meat or dairy leftovers, do so sparingly and keep the coop clean to deter pests.
What to Feed for Strong Eggs
Egg production draws protein, energy, and minerals daily. Layers need a steady 16% protein base, adequate methionine, and free-choice calcium with vitamin D3 in the feed to aid absorption. Offer oyster shell in a separate container so each hen can self-regulate. Keep birds hydrated and reduce stress with consistent routines, adequate space, and roughly 14–16 hours of light during peak production months. Healthy hens on a complete feed don’t need fancy extras to lay well, just steadiness.
Age Matters
Chicks from day one to about eight weeks need high-protein starter with small particles they can easily eat. Give chick-sized grit only if you add treats. From eight to eighteen weeks, grower feed sustains steady development without excess calcium. Switch to layer feed around first eggs or 16–18 weeks, whichever comes first. Mixed flocks often do best on an all-flock or grower feed with a separate oyster shell station so non-layers aren’t overloaded with calcium. Roosters benefit from the same balanced feed without the extra calcium.
What Is a Chicken’s Favorite Food?
It varies by bird and season, but larvae and mealworms rank high. Many flocks rush for melon rinds, corn kernels as an occasional treat, or tender greens. Favorites are fine for training and enrichment, but they should not replace core feed. If treats climb too high, you can see loose stools, feather pecking from amino acid gaps, or a dip in laying.
Fermented Feed Basics
Moistening feed and letting it ferment for a day or two can improve palatability and reduce dust and waste. Use clean containers, cover with water, and stir daily. A mildly sour smell is normal; any foul or moldy odor means discard and start fresh. Fermented feed can support gut health, but consistency matters more than method. If it complicates your routine, dry feed is perfectly fine.
Budget-Friendly Feeding
If you’re exploring how to feed chickens without buying feed, set guardrails. You can sprout grains or grow fodder mats of wheat or barley for fresh greens. Composting systems and black soldier fly larvae bins convert scraps into protein. Plant mixed pasture with grasses and legumes and let runs rest to recover. Save safe kitchen scraps like leafy trimmings and vegetable peels (excluding the unsafe list). Even with these strategies, a complete feed is still the easiest way to guarantee vitamins and essential amino acids. If you reduce purchased feed, watch body condition, egg quality, and behavior closely.
Storage and Setup
Feed lasts longer when kept cool, dry, and sealed. Use metal bins or tough plastic containers with tight lids. Rotate stock so the oldest bag is used first. Choose feeders that reduce waste—treadle feeders keep rodents out, gravity feeders are simple, and DIY PVC feeders can work if kept dry. Waterers with nipples stay cleaner; in freezing weather, plan for heated bases or frequent refills. Align all setups to be easy to clean—clean systems prevent disease and protect feed quality.
Seasonal Adjustments
In summer, shade the run, keep water cool, and offer electrolyte water during heat waves. Provide water-rich treats and avoid heavy grains in the hottest hours. During the fall molt, shift a bit higher in protein with all-flock feeds or added larvae; feathers are protein-intensive. In winter, offer slightly more energy, a warm mash on frigid mornings, and frequent checks to prevent frozen water. In spring, the pasture flush provides greens and bugs—great for enrichment, but keep the base feed steady.
Troubleshooting Diet Problems
Thin or soft shells usually point to inadequate calcium or poor calcium absorption; confirm that oyster shell is available and that feed includes vitamin D3. Feather pecking can stem from low protein, boredom, crowding, or limited foraging—solve it with space, enrichment, and a small protein boost within a balanced feed. A sudden drop in appetite might signal illness, spoiled feed, or heat stress; check feed freshness, water temperature, and bird behavior. Obesity and fatty liver can follow heavy scratch or treat habits; bring treats back under 10% and emphasize complete feed.
Where Do Chickens Live
Healthy diets work best in healthy housing. A dry, draft-free coop with good ventilation and secure roosts protects respiratory health and encourages normal feeding and resting cycles. Nesting boxes with clean bedding prevent egg eating and contamination. A safe run with firm footing and protection from predators allows for daily movement and foraging. A good environment reduces stress, which translates directly into better feed conversion and steadier laying.
What Do Chickens Eat in Minecraft
In the game, chickens eat seeds. It’s a simplified mechanic that helps with breeding. Real chickens enjoy seeds too, but seeds alone lack balanced protein, vitamins, and minerals. The real-world equivalent is a complete feed as the backbone, with seeds as a tiny treat.
How Much to Feed
As a rule of thumb, an adult laying hen eats roughly a quarter pound of feed per day, more in cold weather, less when foraging is excellent. Offer feed free-choice so dominant birds don’t hoard meals. If you prefer scheduled feeding, watch closely to ensure timid hens get their share. Remove leftover wet feed at day’s end to prevent mold.
What Do Chickens Eat on a Budget
Focus your dollars where they count. Buy a reputable complete feed, then stretch flavor and enrichment with homegrown greens, seasonal garden extras, and small amounts of larvae. Build a basic fodder tray for winter freshness. Use a covered feeder to reduce waste, and keep rodents out with storage discipline. You’ll spend less by protecting what you buy.

What Is the Main Feed for Chickens?
The main feed is a complete ration: starter for chicks, grower for pullets, layer for active layers, or an all-flock feed with separate calcium. This is the primary feed across settings because it locks in the nutrient balance birds need every day.
What Do Chickens Eat Naturally
They naturally seek a mix of seeds, short greens, insects, and small invertebrates, shifting with the season. This instinct is useful—give them safe access to forage when possible, and let complete feed cover the gaps.
Final Thoughts
When you map out what do chickens eat across ages and seasons, a simple pattern appears. Start with a complete feed, keep water clean and constant, offer grit and oyster shell as needed, and fold in safe treats for enrichment and seasonal support. Observe your flock. Healthy birds are curious, active, and steady at the feeder. Small, thoughtful adjustments beat trendy fixes every time.
