I have my rooster trained to hop on the perch in the corner with his back to me in there outdoor run. I tap on the fence and he jumps up on the perch while I open the door and feed them. He stays on the perch until I'm done. But, I know that he will continue with progressive aggression and I have to do something because now he knows when I'm going in the coop and runs in quickly to try to attack me.
