I have feed my chickens chopped up pieces of carrots, leaves of weeds and plants, chopped up pieces of noodles, etc. But it seems that the only things my 5 week chickens eat is grass and their store bought feed. I have supplied them "grit" in the form of small stones from the road/sidewalk. I thought that chickens could eat practically everything? So what can they actually eat? Oh, and another question, I've heard that chickens can eat yogurt, how do you feed them it?
