I'm still fairly new to chickens and had a recently aggressive RIR roo that did this to one of my BR roo's. Was able to rehome RIR as he'd attacked me and my daughter and had enough after this. But I cleaned with normal saline and sprayed with blu-kote so half his comb looks discolored now, but mainly wondering if there is anything else I should do or be watching for? Have him cooped by himself for now as I'm afraid out other large BR roo would peck at it and he has picked on him some today. I also grabbed the large BR roo by his legs and had upside and carried him for a minute as I've read that could help with establishing dominance? Any advice is very very much appreciated. Thank you!!!!
