If you’ve got backyard chickens, you know how fast those hungry beaks can go through a pile of greens.
Instead of buying bagged feed additives or constantly replanting short-lived crops, what if you could grow your own all you can eat buffet for your flock?
That’s where perennial plants come in. Once established, these hardy herbs, trees, and groundcovers keep producing fresh forage for your chickens without needing to be replanted every season.
They’re natural, nutritious, and often serve double duty by improving your soil, repelling pests, or even adding color and scent around the coop.
1. Comfrey (Symphytum officinale)
Comfrey is one of the most valuable plants you can grow for chickens. Its broad, nutrient-dense leaves are packed with protein, calcium, potassium, and trace minerals that support strong eggshells and healthy feathers.
This deep-rooted perennial pulls nutrients from deep in the soil, making it a natural fertilizer booster for the whole garden.
Chickens love the tender young leaves, but they’ll strip the whole plant if you let them. It’s best to grow comfrey just outside the run and cut it back regularly to toss into their coop or compost pile.
Once planted, it comes back strong every year and handles repeated harvests like a champ.
2. Mulberry (Morus alba, Morus nigra)
If you’ve got space for a small tree, mulberry is a multi-purpose gift to your chickens.
In early summer, the tree drops sweet, protein-rich berries that your flock will gobble up the moment they hit the ground. The fruit is not only delicious but also supports energy and weight gain during the laying season.
What many don’t realize is that the leaves are also edible and nutritious for chickens.
Mulberry trees grow fast, tolerate pruning, and offer shade for the run in summer. Bonus, their fallen leaves are rich in calcium and minerals, adding value to compost or bedding.
3. Chickweed (Stellaria media)
Chickweed may be considered a weed in some gardens, but chickens treat it like a delicacy. Its soft, tender leaves are full of vitamin C, calcium, and antioxidants.
It grows best in cool seasons and can handle light shade, making it perfect for growing in between coop areas or under shrubs.
This plant reseeds easily, so once you’ve got a patch going, it tends to come back on its own.
Just let a few plants go to seed, and the chickens will enjoy snacking on both the greens and seed heads the next season.
4. Lemon Balm (Melissa officinalis)
This calming, lemon-scented herb isn’t just pleasant to grow, it also helps soothe your chickens. Known for its mild anti-stress and antimicrobial properties, lemon balm can support a healthier, more relaxed flock.
Chickens will occasionally nibble on the leaves, but the scent itself works wonders by repelling flies and mosquitoes around the coop.
It grows well in part shade, returns reliably every spring, and spreads gradually without becoming invasive.
You can also dry the leaves and mix them into nesting boxes for a coop that smells as good as a herb garden.
5. White or Red Clover (Trifolium repens, Trifolium pratense)
Clover is one of the best living groundcovers for chicken runs and pasture areas. It’s rich in nitrogen, grows low to the ground, and chickens happily forage the leaves, flowers, and any bugs it attracts.
It also improves soil health by fixing nitrogen naturally, so your chickens fertilize while they snack.
Clover handles foot traffic well and comes back every year with minimal care. It’s ideal for rotating forage zones or tucking into open garden paths between raised beds.
6. Oregano (Origanum vulgare)
Oregano is more than a pizza topping. This hardy perennial is a known immune-booster in poultry.
It contains natural antibiotics that may help reduce the risk of respiratory illness and bacterial infections in chickens. Some farmers even use it in homemade feed blends to keep flocks strong during stressful periods.
Grow oregano in sunny spots and let it spread. Chickens may peck at it fresh, or you can dry and crumble it into their feed.
7. Yarrow (Achillea millefolium)
Yarrow is a powerhouse in any herbal chicken garden. Its feathery foliage is rich in minerals and known for its wound-healing and digestive support properties.
Chickens are naturally drawn to the soft leaves and flowers, and the plant also attracts ladybugs and parasitic wasps that reduce pests in your yard.
This perennial thrives in poor soil, tolerates drought, and requires very little maintenance. A perfect border plant for chicken runs or low-care garden zones.
8. Plantain (Plantago major)
Another common weed with hidden value, plantain grows in compact rosettes and offers broad leaves that are packed with calcium, vitamins A and C, and natural anti-inflammatory compounds.
Chickens happily eat the leaves and seed heads. Let a patch of plantain grow wild near your coop or pasture, and it will reseed itself every year.
It’s one of the easiest greens to keep going with zero maintenance, and chickens seem to love it even when other options are available.
9. Bee Balm (Monarda didyma, Monarda fistulosa)
This colorful herb is a pollinator magnet and a garden-friendly treat for chickens.
Bee balm has antifungal and antibacterial qualities, and its soft leaves are lightly minty, which chickens may peck at on warm days.
Beyond the health benefits, bee balm’s flowers make your coop or garden area more beautiful. It prefers sun, grows 2-3 feet tall, and returns with vigor each year once established.
10. Alfalfa (Medicago sativa)
Alfalfa is a nutrient-dense forage crop that grows deep roots and comes back year after year with proper care.
It’s high in protein, calcium, and vitamins, making it a fantastic boost for laying hens. You can let chickens graze alfalfa directly or cut it and dry it for winter feed.
Because it takes time to establish and prefers full sun, alfalfa is best grown in dedicated grazing plots or rotated sections where chickens can forage lightly and the plant has time to regrow.
