I have 4 hens and a rooster. He has been here for a couple weeks. The hens, they all came from the same home, and have only been here for about 4 days.. (My first flock) One of the hens seems to be left out when I give treats, when I spread scratch, if another hen wants water or if she touches the rooster she gets pecked by the same hen every time. She doesn't let her sleep on the roost. I watched "Monkey" (my bully) peck her until she went to the ladder last night! She gets pecked for doing anything! Is there anything I can do to stop and prevent this? Is this normal? "They sleep on top of the nesting boxes"
