In short: Pasture raised chickens usually receive a complete grain ration as their main food. They also eat insects, seeds, tender plants and other forage from the ground. Forage typically contributes a small share of total intake, though the amount varies widely by farm, season, breed and feed access.

Pasture raised does not mean grass only. The feeder supplies the dependable nutrition, while the field adds the part shoppers can see.
| Main food | Complete layer or broiler ration |
|---|---|
| Forage | Usually a small share of total intake |
| Layer feed | Protein, calcium, energy, vitamins and minerals |
| Meat-bird feed | Higher-energy growth ration, adjusted for age |
| USDA pasture standard | No single definition for poultry |
| Grass fed label | Not a standard chicken feeding claim |
| Typical layer intake | About 0.25 pound of complete ration daily, with variation |
The short version
- Complete feed supplies the nutrients pasture cannot reliably provide
- Forage includes insects, seeds, tender plants and fallen grain
- Layer and meat-bird rations differ because their bodies have different jobs
- Pasture raised has no single USDA poultry standard, so farm practices matter
- Ask how the birds move, what feed they receive and how the ground looks
What are pasture raised chickens fed?
A pasture raised chicken gets a complete ration from a feeder, then searches the ground for extra food. The ration supplies dependable energy, amino acids, calcium, vitamins and minerals. Pasture adds variety, not a replacement meal.
A hen may scratch through grass and weeds for hours. Her finds change with the ground and the season. A laying hen often eats roughly a quarter pound of complete ration daily, though size, weather, production and forage change the amount.
- Insects and larvae, including beetles, grasshoppers and fly larvae
- Tender grass and broadleaf plants such as clover, dandelion and plantain
- Seeds, fallen grain and small pieces of fruit
- Worms and slugs after rain, plus grit for grinding food in the gizzard

Your flock gets the tallest and longest moveable enclosure of the three — 48" H x 168' L (over 1,700 sq ft) — so birds rotate onto fresh ground while double-spiked posts and guylines keep the net upright on uneven pasture.
Layer and meat-bird diets
Layers need feed built for egg production. Their ration supplies protein, energy and calcium for the egg and its shell. Grass and insects can add nutrients, but their amounts are too unpredictable to formulate the whole diet.
Meat birds need a different plan. A broiler ration supports rapid muscle growth and changes as the bird ages. A slower-growing range breed may spend more time searching for food, but it still needs a complete ration to finish well. Before you commit to anything, it is worth looking at how the cloacal kiss works.
- Layer feed: formulated for laying hens and shell production
- Broiler starter: supports young chicks during early growth
- Broiler grower or finisher: supplies energy and protein as meat birds mature
- Breeder feed: supports reproduction rather than ordinary table-egg production
What pasture labels mean
The USDA does not have one poultry definition for “pasture raised.” Farms can use the phrase while following very different routines. One flock may move across green paddocks. Another may reach a small outdoor yard with little vegetation.
Free range is also narrower than many shoppers expect. USDA rules concern outdoor access, not a guarantee of green pasture, daily use or a particular stocking level. Cage free describes indoor housing without cages and says nothing about outdoor access.
Organic concerns certified feed and production rules. Organic poultry must receive organic feed, and USDA organic rules include outdoor access, with exceptions and detailed conditions. Organic does not automatically mean birds spend the day on pasture. Non-GMO and soy-free describe feed ingredients, not how much time birds spend outdoors. A pasture claim does not guarantee either one. Before you commit to anything, it is worth looking at age for chicks to eat scratch.
| Label | What it addresses | What it does not guarantee |
|---|---|---|
| Pasture raised | Farm-specific claim about outdoor living and forage | A fixed space, schedule, stocking level or feed formula |
| Free range | USDA outdoor-access requirement for covered poultry products | Green ground, regular use of the outdoors or pasture rotation |
| Cage free | Indoor housing without cages | Outdoor access or pasture |
| Organic | Certified organic feed and production rules, including outdoor-access requirements | A specific pasture routine or time outside |
| Non-GMO or soy-free | Specific feed-ingredient choices | Outdoor access or a pasture routine |
| Grass fed | A term used for grazing livestock such as cattle and sheep | A standard chicken feeding claim |
Pasture changes with the season
Chickens cannot digest long grass as efficiently as grazing animals. They choose tender shoots, seeds and insects instead. Their gizzards grind food, but grinding does not turn tough cellulose into a full diet.
Spring pasture may offer insects, clover and fresh shoots. Summer can bring seeds and mature plants, while hot weather may reduce insect activity. Fall supplies less tender growth. Snow or frozen ground can leave little forage, so the feeder carries nearly all of the nutritional load.
Yolk color can deepen when hens eat more carotenoid-rich plants. Shade also changes with feed ingredients, breed and individual birds. Treat a darker yolk as a clue, not proof of pasture access. For the detail, see our notes on cost factors in broiler production.
- Spring: insects and tender plants often become more available
- Summer: forage composition depends on rainfall, heat and plant maturity
- Fall: seeds may remain while insects and soft growth decline
- Winter: birds depend heavily on stored feed when ground forage disappears
Effects on eggs and meat
Forage and flax-based feeds can raise egg omega-3 levels somewhat, but the effect depends heavily on the base ration. Pasture access alone does not predict a specific nutrient result.
Pasture can affect an egg's appearance. Carotenoids from plants may produce a deeper yolk, though feed formulas also affect color. Meat birds may develop firmer texture when they move more and grow more slowly. Breed, age and cooking method affect the result too.
Outdoor space gives birds room to scratch, dust-bathe and search for food. Rotation helps keep that space usable. It also spreads manure and lets plants recover between visits. We cover chickens' visual field in its own article.
- Forage adds variety to a complete ration
- Pasture access supports scratching and dust bathing
- Some feed formulas can raise egg omega-3 levels
- Rotation can spread manure and protect plant growth
- Land, fencing and labor raise the price
- Winter conditions can sharply reduce natural forage
- The label may hide large differences between farms
- Pasture alone does not predict better meat or eggs
Finding local pasture poultry
Farmers markets offer a quick way to find local producers. EatWild and LocalHarvest list farms in many areas, though coverage differs by state. County extension offices, state agriculture directories and local buying groups can also point you toward producers.
Egg layers are usually sold by the dozen or through a weekly share. Meat birds are often reserved months before processing. Breed affects availability: Cornish Cross birds grow quickly, while slower-growing range breeds usually take longer to finish.
Visit if the farmer allows it. Look for vegetation, shelter, clean water, feeders and signs of regular movement. You do not need to calculate a national stocking figure. Watch whether the ground can recover.
- Search local farm directories and shortlist nearby producers
- Use the questions below when contacting sellers
- Ask meat producers about breed, feed and processing dates
- Visit the farm or request current photos of the paddocks
Questions for the farmer
Use a few practical questions before buying. The answers should fit together. Birds cannot forage well on ground that is bare, crowded or rarely opened.
- How do you move the birds? Look for a clear schedule, paddock plan or mobile-coop routine.
- What complete feed do they receive? Ask for the feed type and whether it is organic, non-GMO, soy-free or another formula.
- How much feed does the flock receive daily? A farmer who weighs feed and leftovers can estimate use for that setup.
- Do laying hens receive oyster shell separately? Ask whether grit is available, especially when birds eat whole seeds or other hard foods.
- What does the pasture look like when birds leave? Standing vegetation shows the ground still provides forage.
- Does the diet change by season or bird type? Layer and meat-bird rations should not be identical.
- Can I see the flock or recent photos? A clear view helps confirm the claim.
Questions people still ask
Do pasture raised chickens still eat grain?
Yes. Most receive a complete layer or broiler ration, offered free-choice or in measured amounts. Pasture adds insects, seeds and plants, but it does not reliably supply every nutrient.
How much forage do pasture chickens eat?
There is no dependable figure for every flock. Forage typically contributes a small share of total intake, with the amount changing by breed, season, pasture and feed access. Farmers can estimate feed use by tracking feed offered, leftovers and bird numbers.
Is pasture raised better than free range?
The terms describe different claims, and neither guarantees excellent management. Free range addresses outdoor access. Pasture raised is a farm-specific phrase, so inspect the ground and ask how birds use it.
Why are pasture raised eggs more expensive?
Pasture farms often carry higher land, fencing, labor and predator-control costs. Feed remains a major expense, even when birds forage.
Can I raise pasture chickens in my backyard?
Only if you have enough ground to move birds before plants disappear. Portable coops, fencing and reliable water help. A permanent bare run will not provide meaningful pasture.
What do pasture raised meat chickens eat?
They receive a complete broiler ration matched to age and breed, plus forage. Slower-growing birds may spend more time searching, but they still need dependable feed for healthy growth.
