While we were gone yesterday, somehow our bantam roo got into the coop with the older chickens. Abraham, our full-grown EE Roo protected his ladies and beat up little Romeo. He was able to fly up and get on a high ledge and stayed there, probably most of the day. When we got home he was bloody under his beak on his neck and very bloody behind his comb. Not quite sure how to treat it, but we cleaned everything and sprayed it with bactine. We've done this twice so far. Any other suggestions?
