It's coming into spring and the boys are not getting along so well as they usually do. I have several young cockerels, four araucanas and one ameraucana. So they have been fighting, mostly minor stuff. Bitten combs, lost clumps of feathers, boys keeping their distance from each other, normal stuff. Sometime during the day while I was at work, one of the araucanas ripped to upper horn off the beak of the ameraucana. Seriously, just the bone of the maxilla is left. I looked VERY closely. The ameraucana has been the big aggressor and plucked clean the head and neck of my cock araucana. I suspect he got revenge. So, bone is truly exposed. Seriously, up to the skin around the nostrils, no horn, just beak bone. My assumption is the bird will go septic. He's been fine so far other than he does not close his mouth all the way but I have seen him eat and carry on aggressively. I am assuming the horn covering will not re-grow. Anyone have something similar happen? If so, what were the results? Has anyone had a bird live with out an upper beak? Should I cull him?
