Nearly killed him before I intervened. This whole batch is about 4 months old. Best I can tell, it's 3 roos and 4 hens in one barn stall. Will the roos continue to fight each other just for dominance? Will I need to remove 2 of the roos and leave just 1 for the 4 hens? Was so hard to see this roo aggressively attacking the other roo. About 1/2 his neck feathers were pulled out, and he was bleeding. He's in the isolation pen now. Suggestions?
