What Can Chickens Eat?

Chickens are omnivores and can eat a variety of foods.

Knowing what to feed chickens is essential for their health and wellbeing. By understanding the types of food that chickens can eat, you can ensure that your flock is getting all the nutrients they need to stay healthy and happy.

The most important thing is to make sure that the majority of your chickens diet comes from a complete source. This can be a pellet or crumble food, or you can even ferment your own feed.

Studies show that animals who receive a steady intake of probiotics through fermented feed have a more robust immune system than those on a standard dry feed diet.

A high quality pellet or crumble dry chicken feed is also a solid choice, especially if you have a very large flock. Here at Wild Mountain Homestead, we let our chickens free-range across our off-grid, mountain property (thank goodness we have Colorado Mountain Dogs to keep them safe!).

I’ve found that they eat a lot less feed, when they’re able to get out and scratch around in the great outdoors. They’re also able to naturally consume a more varied diet. In addition to their feed, they can search for bugs and peck at plants. They can be voracious and cause a lot of damage scratching, so I recommend fencing them out of the garden.

While roaming outside their coop and run, they’re also able to naturally find grit. And we provide oyster shell next to the feed for added calcium.

As a working farm, with a large homestead garden we love to share extra fruit and veggie scraps with our flock of chickens.

Author Mallory Paige loves her chickens and wants to make sure they have an optimal diet.

So if you’re unsure what to feed your flock, here is a list of the best treats for chickens:

  • Mealworms
  • Scratch Grains
  • Lettuce
  • Kale and Swiss Chard
  • Cucumbers
  • Squash and Pumpkins
  • Broccoli
  • Mint
  • Oregano
  • Parsley
  • Cilantro
  • Basil

I’ve also found that chickens really enjoy a little bit of watermelon or other juicy fruit on a hot summer day. We’re growing strawberries (in Colorado!) and the chickens absolutely devour any berries we share with them.

There have also been interesting studies and anecdotal on the benefits of giving chickens fish meal or other meat protein sources (I’ve heard of everything from letting them clean a deer carcass to raising tilapia specifically for the chickens).

This may depend on your personal feelings about consuming animal protein, but it is an interesting point to consider. Feeding right won’t necessarily increase egg production, but it will ensure chickens are laying the optimal number of eggs a day.

What Can Chickens NOT Eat?
