What? Chickens are carnivores? They don't like vegetables or vegetable matter?From your post I get the impression that you are feeding a diet high in vegetable matter. Chickens dearly hate a vegetarian diet, hens for the lack of a better description are Steak & Steak feeders, regardless of what groups like PETA may say.
That's ridiculous. Sure they'll eat meat but I don't see chicken feed listing chicken or beef as main ingredients.
My chicken feed is mostly corn and I don't feed them meat except when I score a nest of baby mice or what they find on their own and they don't run around attacking and killing each other for their blood lust to get some meat in their guts.
Guess I can quit worrying about predators I didn't know my chickens were the real predators. Beware coyotes I've got enough birds to take you down.
