After a week of having my queen hen peck at the other girls at night I have put her in chicken jail. She is fine during the day but as the sun goes down and everyone heads to the coop for the night she will peck anyone that steps on her roost in front of the three nest boxes. There are 4 roost bars but everyone wants to roost in the same place. I tried to accept it as pecking order, I tried to hold and pet her until dark then put her in but she still pecked. I even pulled her feathers after I saw her peck but nothing worked. Tonight I snatched her up and put her in a dog kennel in my husbands shop. She'd better get a better attitude!
