Everywhere online always said roosters start mating 4-5 months. Today when I was in the coop I saw my almost three month old probably mating with my older hen or attacking it. He pulled out two feathers as well before I could stop it. Is it normal for him to do it so young? I also have several other roosters if that makes a difference, possibly worried about competition or something? Don’t worry I’m not keeping the roosters just haven’t got rid of them yet because I thought I had more time. I recently just hatched them and never in my right mind would have expected to get this much. Any advice/answers will be helpful at this point.
