Are Chickens Omnivores?

Ever wondered what types of food your backyard chickens can eat? In this blog post, we’ll dive into the dietary habits of chickens and explore whether they are omnivores, herbivores, or carnivores.

Are Chickens Omnivores?

Yes, chickens are indeed omnivores. They have a diverse diet consisting of both plant-based and animal-based food sources, making them well-adapted to consume a wide range of nutrients.

Understanding Chicken Diets and Dietary Habits

Chickens are known for their ability to eat a wide variety of food sources. In order to maintain a balanced and healthy diet, chickens consume both plant-based and animal-based foods. By understanding their dietary habits, you can ensure that your backyard chickens get the nutrients they need for optimal health.

A Closer Look at Chicken Food Preferences

As a chicken owner, you might have noticed that your flock often happily scratch at the ground, foraging for anything that looks appetizing. Chickens are curious by nature, so let’s examine what foods they naturally gravitate towards in their quest for nutrition.

Plant-Based Foods

Chickens are as fond of plant-based foods as they are of the other types. Some common plant-based foods that chickens enjoy include:

  • Grains, seeds, and nuts (e.g. corn, wheat, oats, and sunflower seeds)
  • Vegetables (e.g. lettuce, peas, spinach, and carrots)
  • Fruits (e.g. apples, berries, and melons)
  • Greens (e.g. grasses, clovers, and alfalfa)

Animal-Based Foods

In addition to plant-based foods, chickens also enjoy a variety of animal-based foods:

  • Insects (e.g. ants, crickets, and mealworms)
  • Worms and other invertebrates (e.g. slugs and snails)
  • Small animals (e.g. mice and frogs)

Why Chickens Need Both Plant and Animal Foods

Chickens require a well-rounded diet to thrive because different types of food provide various essential nutrients. While plant-based foods offer carbohydrates, vitamins, and minerals, animal-based foods provide proteins and fats that are critical for maintaining a healthy body and producing eggs. Let’s explore some of the key nutrients chickens need and where they come from:


Chickens require a sufficient amount of protein in their diet for muscle development, feather maintenance, and egg production. Animal-based foods like insects, worms, and small animals are excellent protein sources for chickens. Plant-based options such as peas, sunflower seeds, and soybean meal can also offer protein for your flock.


Carbohydrates provide energy to chickens, allowing them to explore, fly, and exhibit normal behavior. Plant-based foods like grains, fruits, and vegetables are excellent sources of carbohydrates for your backyard flock.

Vitamins and Minerals

Vitamins and minerals are essential for promoting a healthy immune system, bone development, and overall wellness in chickens. Plant-based foods like leafy greens, vegetables, and fruits are rich in vitamins and minerals, while animal-based foods offer additional nutrients such as calcium and phosphorus, which are important for eggshell development.

Feeding Your Backyard Chickens

Now that we understand the dietary needs of chickens, let’s discuss the best ways to provide a balanced and healthy diet for your flock. Feeding your chickens appropriately can help ensure their happiness, productivity, and overall health.

Commercial Feed Options

Many chicken owners opt for commercial feeds to provide a nutritionally complete and balanced diet for their flock. Commercial feeds are formulated with the necessary nutrients, including proteins, carbohydrates, vitamins, and minerals, specifically tailored for chickens at different stages of their life. Some types of commercial feeds include:

  • Starter feed: For chicks up to 6-8 weeks old
  • Grower feed: For adolescent chickens aged 8-20 weeks
  • Layer feed: For adult chickens that are laying eggs

Supplementing with Natural Foods

While commercial feeds can provide a well-rounded diet, some chicken owners like to supplement their flock’s diet with natural food sources. Providing access to grassy areas for free-ranging or offering vegetables, fruits, and insects can improve your chickens’ diet and ensure they get a wider variety of nutrients:

  • Free-ranging: Allowing your chickens to roam and forage can provide access to insects, worms, grass, and other natural food sources.
  • Garden treats: Offer fresh vegetables or fruits (in moderation) as treats, which can help provide additional vitamins and minerals. Always ensure you are only feeding your chickens safe and appropriate produce.
  • Insect supplementation: Adding insects such as mealworms, crickets, or black soldier fly larvae to your chickens’ diet is a great way to boost protein intake and promote natural foraging behaviors.

What Not to Feed Your Chickens

While chickens will eat a wide variety of foods, it’s important to be aware of potentially dangerous or toxic items that should be avoided. Ensuring that your flock doesn’t consume harmful substances can help keep them healthy and thriving. Here are some foods to avoid feeding your chickens:

  • Processed foods: Junk food, salty snacks, or sugary treats should not be fed to chickens, as they can lead to obesity and other health issues.
  • Avocado: The skin and pit of avocados contain persin, a toxin that can be harmful to chickens.
  • Chocolate: The theobromine found in chocolate can be toxic to chickens and should be avoided.
  • Raw or undercooked beans: Raw or undercooked beans contain a toxin called phytohaemagglutinin, which can be dangerous for chickens. Beans should always be properly cooked before feeding them to your flock.
  • Green potatoes or tomatoes: Green potatoes and tomatoes contain solanine, which can be toxic to chickens. It’s best to stick to offering ripe fruits and vegetables to your flock.

Monitoring Your Flock’s Health and Diet

Regular monitoring of your flock’s health and diet is essential in ensuring their well-being. Keep an eye on the condition of your chickens, their behaviors, and their egg production to make adjustments to their diet as needed. By providing a balanced and nutritionally complete diet, you can keep your backyard chickens happy and healthy, enjoying their omnivorous lifestyle.

Maintaining a Healthy Feeding Environment

Creating a healthy feeding environment for your backyard chicken flock is essential for their overall well-being. By ensuring that they have access to clean and fresh food and water and keeping their feeding area organized and sanitary, you can help promote optimal health for your chickens. Here are some tips to maintain a proper feeding environment:

  • Provide clean and fresh water daily, making sure that the water sources are easily accessible to all flock members.
  • Regularly clean and sanitize feeders and waterers to prevent the build-up of bacteria that can cause illness.
  • Avoid allowing food to become wet or moldy, as this can lead to the growth of harmful fungi and bacteria.
  • Offer appropriate feed storage containers to keep food dry and pest-free.
  • Monitor for any signs of contamination, such as mold or insects, and promptly address any issues.

Feeding Chickens at Different Life Stages

It is important to take into consideration the different nutritional requirements of chickens at various life stages. From chicks to laying hens, each stage requires specific nutrients to ensure overall health and productivity. Below is a brief overview of the different stages and their unique feeding requirements:


Until they are six to eight weeks old, chicks should be fed a high-protein starter feed specifically designed for their nutritional needs. This feed contains approximately 18-20% protein and provides essential nutrients like amino acids, vitamins, and minerals to support their rapid growth and development. It is important to offer unlimited access to this feed, allowing chicks to eat as much as they need.


From eight to twenty weeks of age, adolescent chickens should be transitioned to a grower feed with 15-18% protein. This feed supports their growing bodies and ensures proper muscle, bone, and feather development. As with the starter feed, it is essential to provide unlimited access to grower feed during this stage.


Beginning at around 20 weeks of age or when your chickens start laying eggs, transition your flock to a layer feed with 15-18% protein. This feed is specially formulated with additional calcium and other nutrients vital for healthy egg production. Your laying hens should have access to layer feed at all times.

Additional Nutritional Supplements

Along with a properly formulated feed, backyard chickens can benefit from additional supplements to enhance their diet and health. Here are some common supplements to consider offering your chickens:

  • Calcium: Providing a calcium source, such as crushed oyster shells or eggshells, can help laying hens to produce strong, healthy eggshells. Calcium supplements can be offered in a separate container or mixed with their regular feed.
  • Grit: Chickens need grit, which is tiny stones or coarse sand, to help break down food in their gizzard. Offer grit in a separate container for your chickens to access as needed, especially if they are not free-ranging.
  • Probiotics: Adding probiotics to your chickens’ water or feed can help promote a healthy gut and support their immune system.
  • Vitamin and mineral supplements: Supplements specially designed for chickens can help ensure your flock gets all the essential vitamins and minerals they need for optimal health.

Providing Your Flock with Enrichment Activities

Chickens are smart and curious animals that thrive when offered opportunities for mental stimulation and engagement. You can further enhance their natural foraging behaviors and omnivorous tendencies by incorporating enrichment activities into their environment. Here are a few ideas for chicken enrichment activities:

  • Hanging fruits or vegetables: Suspending produce like cabbage or melons from their chicken coop or run can be entertaining and provide an additional source of vitamins and minerals.
  • Pecking blocks or toys: Pecking blocks or toys filled with seeds, grains, or even insects can give your chickens a fun activity that encourages their natural behaviors.
  • Scratch areas: Creating designated scratch areas with sand or loose soil can keep your chickens entertained and prevent boredom, enabling them to dig around and find treats hidden beneath the surface.
