Today while I was waiting for the girls to go up to roost, I noticed my BO had wound right behind her comb. She was not bleeding, but it appears to be a very deep gash. It isn't very clean looking, not in terms of germs, but more like how the slice was. It looks like something/the other hens were pecking her. This is unusual to me because she was never at the bottom of the pecking order. It seems since they have been confined to the run and coop, the entire pecking order has been re-arranged. What do I do to help her?!
