Plants Chickens Won’t Eat: The Complete Guide

By Kimberly



We all know that a free-range lifestyle is better for chickens, but this sometimes comes at the cost of your garden. Chickens can destroy a garden or young veggie patch very quickly. In order to strike a balance between the free-range chickens’ lifestyle and the garden, what plants are chicken-proof?

Chickens have good instincts about what food is safe for them, and they generally won’t eat poisonous plants. Most chickens won’t eat certain aromatic plants either, such as mint or lavender because they don’t like the taste.

A bare garden isn’t very attractive or beneficial. So, how can someone with a green thumb still have a green garden with chickens around? Take a look at our complete guide to the plants that chickens won’t eat.

Why is it Good to Have Chickens in Your Garden?

Having chickens in the garden is fantastic for the land and for chickens. Chickens are happier outside where they can scratch around and enjoy the sunshine. Your garden will benefit from a chicken’s natural tilling technique, and chicken manure improves the soil quality.

Chickens are the best form of natural pest control in a garden because they love eating bugs and larvae. They also turn plants into nutritious mulch.

When chickens are given access to a compost heap, they will gladly turn it over. Just make sure there’s nothing on it that’s unsafe for chickens before letting them have it.

When chickens range freely, they have a more diverse and nutritious diet. It’s also good for their well-being because they get to practice their natural habits, such as scratching and dust bathing. Free-range chickens produce tastier and more nutritious eggs because they’re healthy and happy.

Many chicken keepers give their chickens an outdoor run to scratch around in. Some chicken runs are fixed to the ground, while others are mobile and easy to move around. Mobile runs are good because chickens strip a run of its greenery very quickly.

Some keepers let their chickens have access to all of their land. If this is you, plan on planting chicken-resistant plants to keep the greenery in the garden.

Are There Plants Chickens Won’t Eat?

Chickens won’t eat tall plants they can’t reach, and they will also avoid eating poisonous plants. However, a hungry malnourished chicken will eat whatever it can find, including poisonous plants.

All chickens are different; some chickens will eat what other chickens usually leave alone. Also, if there’s nothing else to eat, chickens will eat almost anything to survive. As far as garden plants go, there are plenty of chicken-resistant plants that most chickens don’t like the taste of.

It’s a good idea to test a plant out first to see if the chickens will eat it. Buy a small specimen and leave it out with your chickens. If the chickens eat it, it’s no great loss. If they don’t, congratulations – you’ve got yourself a chicken-resistant plant.

Groundcover Plants Chickens Won’t Eat

Chickens won’t eat groundcover plants they don’t like the taste of, like creeping mint or rosemary. Some groundcover plants, such as low blueberry bushes, are edible for chickens. Chickens will eat the fruit from these without destroying the plant.

Groundcover plants are good if you have chickens because they’re dense, quick-growing, and protect the soil. They will help bring some greenery to the garden, and some groundcovers are aromatic and produce flowers.

For some ideas of suitable ground cover plants that chickens won’t eat, take a look at the list below.

Shrubs That Chickens Won’t Eat

Chickens won’t eat tall shrubs they can’t reach, and they generally won’t eat aromatic shrubs. Shrubs are tough and woody, like small trees, and chickens seem to leave most shrubs alone.

Shrubs are great for a chicken run because they provide shade and shelter for chickens. However, chickens will eat young immature shrubs because they’re more palatable. So, all young shrubs must be protected from chickens.

Signs of Poisoning in a Chicken

If a chicken has eaten something toxic, the symptoms may be mild or severe depending on what they’ve eaten. A poisoned chicken will become lethargic and lose its appetite. They may also drink excessively and have discolored green droppings.

Poisons can kill a chicken pretty quickly, while others act more slowly. Long-term signs of poisoning include weight loss and the chickens will be in poor condition.

If you’re worried about your chickens’ health or think they’ve eaten a poisonous plant, don’t hesitate to get in touch with your vet.

What Can You Plant Around a Chicken Run?

The best things to plant around the chicken run to give them shade and cover the ground are chicken-resistant plants. It’s a good idea to have plants around the chicken run for the chickens to eat and forage from. 

Many plants such as fennel attract insects to lay larvae – which chickens love to eat. Oatgrass, white clover, and leafy greens will provide plenty of forage and lots of extra nutrition around the chicken run.

Chickens like to eat herbs too. Many herbs have therapeutic properties for a chicken, such as a thyme, which is antibacterial. Most chickens love to eat comfrey, thyme, sage, and oregano.

For some pretty color around the run, plant flowers such as dandelions, marigolds, and nasturtiums, these have medicinal and antiparasitic properties. Or, grow some sunflowers and feed the dried seeds to your chickens as a treat. 

Berries make a delicious and nutritious treat for chickens as well as vine fruits like watermelon and grapes. Chickens will love helping themselves to the fruit. You can also grow fruits and vegetables such as cucumber, corn, peas, squashes, and pumpkins for the chickens to eat.

It’s good to plant a mix of edible and chicken-resistant plants around a chicken run. However, before putting a new plant around the run, make sure to introduce it to the chickens slowly. Chickens might get ill if they eat too much of a new plant all at once.

Things You Should Never Feed To Chickens

Chickens can eat most foods, including meat and animal products. However, some foods are highly toxic to chickens and can make them very ill or even kill them. You should never feed chickens moldy or rotten food or vegetables from the nightshade family.

Take a look at this important list below of the things you should never feed to chickens.

  1. Alcohol, caffeine, or soft drinks
  2. Moldy or rotten food
  3. Processed, salty, fatty, or fast food.

How Do I Keep Chickens Out of My Garden?

In order to grow veggies or plants that chickens love to eat, plant them in a place where the chickens can’t get to them. Make a fenced-in garden or put plants in raised beds or boxes to keep them safe from chickens.

To keep chickens out of the garden with a fence, make sure it’s at least 2 or 3 feet high and without a top bar to land on. Chickens usually won’t be able to jump over a fence this tall. If there are some good fliers in the flock, you might want to make the fence taller, though our best fliers can easily jump over a 4-foot fence. Thankfully, they don’t jump the 6-foot vinyl fence!

Also, make sure the fence runs right down to the ground and that it’s narrow enough so the chickens can’t squeeze through.

Another option is to cover the veggie garden with chicken-proof netting, or use raised beds at least 2 feet high. Alternatively, you could grow plants in hanging baskets to keep them out of a chicken’s reach.

If you need to give your chickens access from one area to another, but you don’t want them getting into the garden, use chicken fencing to create tunnels between their allowed spaces. That way, they can get where they need to, but they can’t get to your garden.

Key Takeaways and Next Steps

It’s good to have plants and shrubs around to provide shade and shelter for the chickens. However, chickens will eat almost anything so choose plants for the garden or chicken run that they don’t like to eat. Grow plants that enrich the chicken’s diet such as berries. 

If there are poisonous plants around, make sure the chickens are always well fed so they don’t eat them. If you do see chickens eating poisonous plants, remove the plants or make them inaccessible to the chickens.
