I often describe chickens as miniature trash compactors – they will eat almost anything you put in front of them. An emphasis should be placed on “almost anything”.
For the most part, we feed our chickens food items they would normally find around the ranch – veggies, fruits, seeds and grains. As a treat or to supplement their diet, we give them meal worms. They are all-natural and give the girls extra nutrients. We may also put a little diatomaceous earth (DE) in their food, as well. This aids in digestion and is a natural de-wormer. Chickens also need some calcium and a little grit in their diets as well. The calcium helps them form a strong outer eggshell and the grit aids in digestion. I usually purchase this supplement kit with oyster shells, DE and grit, and add a little each day to their feed.
