These are all Americaunas. My poor pullet. They have been together for a week without any fighting at all. I opened up the coop this morning to let them out, and my beautiful black and white pullet has a large wound on the back of her head about the size of a nickel. The skin is just completely seperated. I thought maybe she got caught on something, but the older hen started trying to peck her as I was holding her. I moved the older hen back into the goat pen where she has lived until a week ago. I moved the pullet from the coop into a cage I had them in before the coop was built. I tried to put some neosporin and a bandage on it, but she works the bandage loose and then ended up opening the wound more, so I settled on just leaving it off. Is there anything else I can do?
