I have 5 hens and a rooster. They all know their pecking order and the get along well during the day. BUT, just before they all go to bed one of the higher hens, Atilla the Hen (Tilli), picks on a lower ranking hen, Mayvis. I have watched it for two weeks now and every night Tilli chases Mayvis and pecks her, pulling feathers out. Mayvis is now going bald on her back from being bullied. Today it was so bad I actually picked up Tilli and carried her away whilst Mayvis went to bed. Sometimes the rooster comes in and stops it but usually he is in bed, I would like to take Tilli away and let her go when Mayvis is in bed and ready but I can't go near the hens without being attacked by the rooster (another problem, nothing works on him. I have tried everything). I have read that chooks bully because they are bored but they just have 2 at least roaming around the garden. How can I keep them entertained during the day when I am away? Their day pen is 30 metres all round so it is pretty big. How can I stop the bullying? Mayvis has a bald patch on her back and getting worse. Mayvis can't outrun Tilli because she is a Light Sussex and Tilli is an Ancona who are very fast chooks. Please help, I don't want Mayvis getting hurt, she is the only one being singled out and the other hens are fine. They are a year old in 2 months.
