Update, good and bad news. Good news, one chick is alive. Bad news, two died one right after hatching and the other stopped developing in the egg and the live chick I have had to be took from the hen while hatching because, the hen tried to harm it. I think this what happened to the chick I found hatched but dead. I was just there to late and assumed the hen would be a good mother. Here is a picture of the live one.
