Good quality, tasty eggs come from healthy, happy chickens. Nutrition plays a vital role in a chicken’s health and well-being, so it’s important to get their diet right. One thing you might be wondering is, what foods are healthy and safe for your chicken to eat?
Chickens can eat a range of things, including meat, grasses, fruits, vegetables, and grains. However, some foods such as avocados and chocolate are highly toxic to chickens, and chickens shouldn’t eat fatty, salty, or processed foods.
If chickens are fed the wrong food, it can be bad for their health, and in some cases, it can even kill the chickens. So, in order to learn more about your chicken’s diet and get a clearer idea about what they can and cannot eat, take a look at our complete guide below.
What Do Chickens Eat?
Chickens are omnivores which means they can digest both plants and meat. However, they need a varied diet, and they can’t survive on just one type of food. Chickens can eat a range of fruits and vegetables as treats, but treats should only make up 10 percent of a chicken’s diet.
The amount of food a chicken needs will depend on its age, breed, size, environment, and season. To give chickens the best diet, learn about their nutritional requirements and feed chickens according to their needs.
Chickens need constant access to fresh, clean water, and they generally drink more in the summer. Chickens also need grit; one example is dirt – to digest their food. If the chickens are kept indoors, grit needs to be provided in their diet.
What’s an omnivore?
In the animal kingdom, each creature is either an herbivore that only eats plants, a carnivore that only eats meat, or an omnivore that eats both meat and plants. The word omnivore comes from the Latin words – Omni, which means everything, and Vorare, which means devour.
Just like humans, chickens are omnivores which means they’re highly adaptable because they can utilize all the different foods available in their environment.
Chickens like to forage and will eat almost anything in their path, including small animals and insects. Chickens will even eat each other if they live in crowded, unsanitary conditions.
What do chickens eat in the wild?
Wild chickens are also known as jungle fowl or feral chickens, and they eat whatever they can get their beaks on. Wild chickens adapt their diet to suit their circumstances and have good foraging instincts. They will scratch and dig to get food.
Wild chickens eat pasture plants and grasses such as buckwheat, clover, dandelions, and bluegrass, as well as wild fruits and berries.
In the wild, chickens also eat a range of insects such as grasshoppers, ticks, termites, spiders, caterpillars, worms, beetles, and their larvae. Chickens will also eat small animals such as lizards, frogs, mice, snakes, and the eggs of other animals.
What do chickens eat on farms?
On a farm, chickens usually eat nutritionally balanced chicken feed and grains, specifically designed for their dietary needs. Farm chickens are usually raised for meat or eggs, so they must have a healthy balanced diet.
The main ingredient in chicken feed is grain and grain by-products, such as canola and soybean meal. It usually contains around 10 percent meat or bone meal fats to boost nutrient levels, texture, and taste.
Approximately 1 to 2 percent of chicken feed is vitamins, minerals, and additives such as micronutrients and enzymes, which are vital for your chicken’s general health.
Farm chickens also eat scratch food in addition to grains. Scratch food is a mix of grains and seeds cut into small pieces so chickens can scratch them up off the floor.
Scratch food lets chickens carry out their natural scratching and foraging behavior, so it’s a good boredom breaker for indoor or farm chickens.
Farm chickens, who don’t have access to insects, love fresh or dried mealworms as an occasional treat. Mealworms are full of fat and protein, so they’re fantastic for chickens during a molt. However, chickens can’t have too much fat or protein. They shouldn’t eat more than ten mealworms per day.
What do chickens eat when they are free-range?
Free-range chickens have the best of both worlds. They get balanced chicken food as well as access to an outdoor diet. Free-range chickens will eat whatever’s available, so they benefit more from a free-range environment diverse with plants and insects.
Enrich free-range chickens’ diets by planting fruit trees and grains around their coop or by leaving wild areas on the land to attract insects.
Free-range chickens will enjoy scratching for bugs on a compost heap or scratching at rotten logs for termites and other insects. A free-range chicken diet can also be supplemented with fruits and vegetables.
What plants do chickens eat? Which do they avoid?
Chickens usually only eat plants that are safe for them, and will automatically avoid poisonous plants or plants they dislike unless they’re malnourished.

Complete List of Fruit That Chickens Can Eat
Chickens can eat a wide range of fruit. Fruit is a fantastic source of fiber and is full of vitamins, minerals, and antioxidants, vital for a chicken’s health and well-being. However, some fruit can be high in sugar, so always feed the fruit to chickens in moderation.

What Chickens Can and Cannot Eat – Frequently Asked Questions
Can chickens eat kudzu?
Kudzu is an abundant, nutrient-rich crop. Some farmers use it as forage for many different farm animals, while it’s seen as a weed that’s taken over the countryside in other areas.
Chickens can eat the vine tips, flowers, leaves, and roots of kudzu, but they shouldn’t eat the mature vines, seeds, and seed pods.
