I have two roosters and only four hens, since I was given one hen and then got five straight run chicks from TSC. All of the chickens are about three months old now, and I think my two roos are already fighting. I think the dominant one is my Cochin roo, and my other one is a booted bantam, Dixon. I noticed today that Dixon has two injuries. On his right foot, there's blood surrounding the base of a feather, and on his head, there's a small, open wound right where his comb meets his head. The head injury seems to be something that another chicken did, probably by pecking on his head, and I don't see why any of my other hens would do that. Do either of his injuries sound bad? Do you think my other roo did it? Do I need to separate the roos? Any advice would be greatly appreciated.
