I know of a Silver lace hen that is only being fed cattle feed because the owner is into cattle and rare;y pays any attention to the hen. The grain and all that stuff consists of Urea. I asked about it to the owner and he me that its good for her and it helps her lay eggs more. I have only see her lay 3 eggs a week. I am concerned for for her well being. She came with three other hens and a rooster but they all died suddenly, I think it is because of the feed. So my question is: Is cattle feed that contains Urea in it good for chickens?
