My Polish roo always gets his head feathers pulled. He actually sort of seems to like having the girls "groom" his topknot... Anyway, tonight he's got crusted blood on his head, I presume from too much picking. Is there something I can use just for tonight to deter the picking until I can get to the feed store? I have icthammol on hand. Would that work? Might have pine tar but it's likey frozen in the horse shed. Thanks!
