Not sure, but I think the one on the left is a rooster and the one on the right is a hen. Any ideas? They are about a week apart. Also anyone know what kind of chickens they are? Or should I just call them "yard chickens"? These were free from a friend, and a good introduction to chickens. The one on the right got attacked and bloodied up several weeks ago by the one on the left. Thus the bald spot at the top of the head. Every since we put them in the yard/coop they have gotten along fine.
