We have a pretty dominant angry rooster, he’s still young (approx 8weeks), he’s the only rooster in a flock with 5 hens. Whenever we enter the run to open the coop he chases and attacks us & he has definitely left his mark. His bite HURTS. Feeding and watering is almost becoming impossible and takes 3 of us just to get it done. We’ve not been able to enter the coop at all, as soon as we go near that end of the run he runs in the coop waiting for us. We walk near the run and he’s inside following and jumping at the fence. He’s not top dog, one of the hens is and although he tries to put her in her place he is always the one to back down. Any advice?
