I previously lived in Vietnam, where my family had a farm. In this farm we had about 20+ chickens (not including the chicks) . We only fed them uncooked rice (and sometimes cooked) for their diet. Their eggs were hard and all and they seemed fine on this diet. In Vietnam, we let our chickens free roam the property letting them eat anything they find. I was wondering if I can do that here in my backyard? (we live in america now) Thank you so much!
