Raising chickens on pasture is one of the most rewarding and sustainable ways to keep a flock. Not only does it reduce feed costs, but it also improves bird health, enriches soil, and creates a more natural environment. One of the most effective ways to support a thriving chicken system is by planting cover crops—plants grown to improve soil, provide forage, and create a healthier ecosystem.
In the United States, where climates range from cold northern winters to hot southern summers, choosing the right cover crops can make a dramatic difference in flock health and land productivity. This guide explores every major cover crop suitable for chickens, including grasses, legumes, leafy greens, grains, and root crops. It also explains how each plant benefits chickens, how to grow it, and how to integrate it into a sustainable pasture system.
🐔 Why Cover Crops Matter for Chickens
Cover crops are traditionally used in agriculture to:
- Improve soil structure
- Fix nitrogen
- Suppress weeds
- Prevent erosion
- Increase organic matter
But for chicken keepers, they offer additional advantages:
- Natural forage → reduces feed costs
- Insect attraction → boosts protein intake
- Shade and shelter → reduces stress
- Cleaner ground → less mud, odor, and disease
- Enrichment → chickens stay active and healthier
A well‑designed cover crop system benefits both the land and the flock.
🌾 Categories of Cover Crops for Chickens
To make this guide easy to navigate, we’ll group cover crops into four categories:

Oats
- Soft blades → easy for chickens
- High fiber
- Cool‑season growth
Best use: Fall planting for winter greens.
Wheat
- Chickens eat both greens and grain
- Good winter cover
- Helps suppress weeds
Best use: Dual‑purpose forage + grain production.
3. Sturdy Seed Providers (High‑Yield Forage Crops)
Amaranth
- Extremely nutritious seeds
- Tall, sturdy stalks withstand foraging
- Leaves are edible too
- Heat‑tolerant
Best use: Summer seed production for chickens.
Grain Grasses (General Category)
Includes:
- Barley
- Rye
- Wheat
- Oats
These grasses provide:
- Tender greens
- Seed heads
- Soil improvement
Best use: Mixed pasture or grain production.
4. Fodder & Root Crops (Dual‑Purpose Greens + Roots)
Daikon Radish
- Fast-growing
- Deep roots break up compacted soil
- Chickens eat both greens and roots
Best use: Soil aeration + winter forage.
Fodder Beets
- High-energy roots
- Large leafy tops
- Excellent winter feed
Best use: Cold‑season fodder.
Turnips
- Chickens eat greens and roots
- Fast-growing
- Excellent fall crop
Best use: Dual‑purpose forage.
Rabe (Broccoli Rabe / Rapini)
- Tender greens
- Fast-growing
- Chickens enjoy leaves and stems
Best use: Cool‑season forage.
5. Pasture Grasses (Durable, Long‑Term Chicken Forage)
These grasses withstand scratching and provide consistent ground cover.
Fescue
- Very durable
- Handles heavy chicken activity
- Cool‑season growth
Best use: Permanent chicken yards.
Perennial Ryegrass
- Fast regrowth
- Highly palatable
- Cool‑season forage
Best use: Northern pastures.
Kentucky Bluegrass
- Hardy and resilient
- Common in U.S. lawns
- Handles scratching well
Best use: Chicken runs and mixed pastures.
Orchard Grass
- Soft, palatable leaves
- Shade tolerant
