Most backyard chicken keepers spend somewhere between $50 and $100 a month on commercial feed without thinking much about it. It’s just part of the cost. But there’s a quieter approach that a growing number of self-sufficient farmers have figured out — growing free chicken food directly on their property using plants that regenerate after every harvest, require almost no ongoing care, and in many cases deliver better nutrition than anything in a feed bag.
None of these plants require a large property, specialized equipment, or a lot of gardening experience. A few of them don’t even need soil. What they share is the ability to keep producing season after season once you get them established — which means the effort you put in once keeps paying off for years. If you appreciate plants like this, you may also enjoy our roundup of perennial crops that keep producing year after year.
Here are five plants worth adding to your homestead if cutting your feed bill is a priority.
Moringa has been feeding livestock on sustainable farms across tropical and subtropical regions for centuries, and the nutritional case for it is hard to argue with. The leaves contain around 27% protein — higher than most commercial feeds — along with vitamins A and C and calcium, which are exactly what laying hens need for strong eggshells and healthy immune systems. Chickens tend to go for fresh moringa leaves eagerly, often before anything else in their feed area.
What makes moringa practical for American backyard farmers is how fast and forgivingly it grows. In USDA zones 9 through 11 it grows year-round outdoors. In zones 7 and 8 it dies back in winter but returns from the roots each spring. In colder zones it can be grown in large containers and brought indoors during freezing months. A single tree can reach ten feet in its first year and produce several pounds of leaves per harvest. You strip the leaflets from the branches and feed them fresh, or dry them for storage during the off-season.
The maintenance routine is simple: prune the tree back to about three to four feet every few months. That’s what triggers new growth and keeps the tree producing dense, tender, protein-rich leaves rather than growing tall and sparse. During peak season, excess leaves can be dried and ground into powder that stores for months — a useful way to bridge the gap when fresh growth slows in winter.
2. Comfrey The Deep-Rooted Perennial That Feeds Itself and Your Flock
Comfrey is one of those plants that rewards patience with almost embarrassing generosity. The roots grow ten feet deep into the soil, pulling up phosphorus, potassium, calcium, and iron that most other plants simply can’t reach. All of that mineral content gets concentrated in the large leaves, which clock in at 20 to 25% protein — comparable to expensive protein supplements — along with the calcium that laying hens depend on for consistent egg production. If you want to understand why deep-rooted perennials are so valuable, take a look at how weeds reveal your soil’s nutrient story too.
Once planted, a comfrey patch returns for decades without replanting. Some patches have been documented producing from the same original planting for over twenty years. The harvest rhythm is simple: cut leaves every four to five weeks during the growing season, wilt them slightly to reduce excess moisture, and feed them to your flock. A single established plant can produce four to five cuttings per season, each yielding several pounds of leaves. Four or five plants can cover a significant portion of a small flock’s nutritional needs during peak season.
Choose your planting location carefully because comfrey doesn’t transplant well once established. A dedicated spot along a property line, garden edge, or near the coop works well. After the first year while the roots are establishing, comfrey becomes nearly drought-proof on its own — those deep roots find water that other plants can’t reach. Beyond that first year it needs almost nothing from you.
3. Azolla The Water Fern That Doubles in Days
Azolla is the outlier on this list — it grows in water rather than soil, which is either a limitation or a major advantage depending on your setup. It’s a floating water fern that doubles its mass every three to five days under the right conditions, making it one of the most productive feed sources you can grow per square foot of space. The protein content runs 25 to 35%, it contains essential amino acids needed for muscle development and egg production, and it delivers vitamins A and B12, iron, and calcium on top of that. Families across Vietnam, India, and the Philippines have been using azolla to feed poultry sustainably for generations.
The setup requires almost nothing: a shallow container — a kiddie pool, a large plastic storage bin, even a half barrel — filled with four to six inches of water, a small azolla starter culture, and a spot with partial sun. Azolla prefers some shade during the hottest part of the day, particularly in southern states. Once established, the harvest cycle is as simple as scooping out roughly half the growth every few days and tossing it to your chickens. The remaining half regenerates back to full coverage within days on its own.
Monthly maintenance involves adding a small amount of diluted organic fertilizer — liquid fish fertilizer or even diluted compost tea — to keep the water nutrient-rich enough to support rapid growth. A single small pool can produce several pounds of fresh feed per week once it’s running. Keeping two or three separate containers provides backup if one crashes due to extreme heat or a sudden drop in water quality, which can happen above 95 degrees Fahrenheit.
4. Tree Collards (Perennial Kale) The Cold-Hardy Green That Produces for a Decade
Most greens grown for chickens are annual crops — they grow, produce, and die, and you start the cycle over. Tree collards break that cycle entirely. They’re a true perennial vegetable that can feed your flock for five to ten years from a single planting, and in mild climates they stay productive almost year-round. The plants grow six to ten feet tall and produce large leaves continuously, packed with vitamins A, C, and K, plus calcium and iron, similar in many ways to traditional collard greens. The leaves are tender enough that chickens eat them readily but tough enough to handle light frosts and keep producing well into fall and winter in zones 7 through 10.
Tree collards don’t produce viable seeds, so they’re propagated from cuttings — which actually makes starting them straightforward. Cuttings root reliably in soil or water within two to three weeks, and our rooting secrets for faster propagation can help speed that process along. If you know someone growing them, a few cuttings are all you need to get started. Otherwise, small starter plants are available from specialty nurseries and homesteading suppliers online, and many university extensions like University of Minnesota Extension offer helpful general guidance on growing kale family crops.
The harvest method is a cut-and-come-again system: take outer leaves weekly and the plant keeps generating new growth from its center. Four to six established plants can supply consistent greens for a small flock throughout the growing season. Annual pruning of woody stems and mulching around the base are the main maintenance tasks — both take minutes and are worth doing to keep plants bushy and producing tender new leaves rather than growing leggy and unmanageable.
5. Amaranth The Self-Seeding Plant That Provides Both Greens and Grain
Most plants on this list give you one thing. Amaranth gives you two: nutritious greens that chickens eat fresh throughout summer, and high-protein seeds that can be harvested or left to drop naturally for fall and winter feed. The leaves are tender and fast-growing. The seeds contain 13 to 14% protein with all essential amino acids and are rich in iron, calcium, magnesium, and B vitamins — a nutritional profile comparable to quality grains, grown in your own backyard. For background on amaranth’s botany and uses, the the University of Florida IFAS Extension has a helpful overview.
What makes amaranth especially low-effort over the long term is its self-seeding habit. Plant it once and it returns every year without replanting. Seeds drop naturally, germinate in spring, and the cycle continues on its own indefinitely. For free chicken food that genuinely runs itself, amaranth is hard to beat, and it fits nicely alongside other vegetables that basically grow themselves. Grain amaranth varieties like Golden Giant or Hopi Red give you the best overall return since they produce both generous leaves and heavy seed heads.
The two-stage harvest works like this: throughout summer, harvest young outer leaves as fresh feed for your flock. As fall approaches, let selected plants flower and develop seed heads. Those seed heads can be harvested, dried, and fed whole to your chickens, or left to drop naturally to self-seed next year’s crop. The only real maintenance consideration is preventing excessive spreading if you want to keep amaranth contained to specific areas — harvesting seed heads at about 90% maturity and drying them fully before feeding or strategic release gives you control without losing the self-sustaining benefit.
One Actionable Takeaway
Rather than adding all five at once, think about how these plants can be positioned strategically across your property to create a layered system that produces year-round without extra effort. Comfrey works well along borders or garden edges where it can stay permanently. Moringa needs a sunny spot with good drainage. Amaranth thrives in open areas where self-seeding is welcome. Azolla lives in containers near a water source. Tree collards placed close to the coop make daily harvesting a natural part of your morning routine rather than a separate task.
Start with one plant this week — even a single moringa cutting, a handful of amaranth seeds, or one comfrey root division. As that first plant establishes and starts producing, the confidence to add the next one comes naturally. That’s how a real self-sufficient feeding system gets built — not all at once, but one productive plant at a time.
