You’re the only one who can decide how much nonsense you want to take from him, and how you want to handle it. I use a hands off approach with my cockerels. I don’t pet, pick up, carry or hand feed. When I’m out with the chickens, I walk with confidence around them. I do not “tread lightly” because I want them to know that I will not be pushed around. I walk through them if they’re between me and where I want to go. If one decides to sneak up on me from behind, I turn around and face him, walk toward him and back him up. Sometimes I just walk toward them until they move away. I move them away from the feeder and waterer just because I can. Basically, I meet their every challenge. I don’t care if they crow or mount a hen in front of me - I’m not a rooster. I just want them to respect my space. I have not had a problem with cockerels or roosters since I have started raising them this way.
