I have a rooster who is missing a few feathers from his chest. I went out today to discover that he had blood all over his chest from an injury. I tried to find what could have hurt him but I couldn't find anything. I'd like to do something to help but my rooster is just plain mean and will attack me instantly if I come near him. Is there a chance that he'll get pecked to death by my hens and my other rooster, even if he is in control of the flock? Also, should I just let it be or should I try? Any suggestions would be helpful. I'm not sure what to do.
