I'm new to having chickens but I've had my hens for a few months and recently got a rooster. He's pretty protective which he should be, except for attacking me. I have been noticing that one of my hens is afraid of him. All the others are quite calm around him. When she comes around he darts at her and she runs away. Just now I was watching them in the coop and he jumped on her and I thought they were going to do the deed. She took the submission pose but what he did nest upset me. Three times he pecked at her head and then stomped her head with his foot. Is this normal behavior? His behavior was the same as when he tries to attack me. Posture...peck...stomp. Help
