I know I've posted a couple of times the last few weeks but I really don't know what else to do! My Hamburg is getting pecked repeatedly by the 3 isa Browns, she now is bald on her back, tail and vent area, and with bloody wounds. I have caught the hens doing it and tried everything recommended, mustard on the hens back, purple spray, no peck spray, put up a mirror and swing and dangled old cds from the roof to distract them, throw scraps daily but I just don't know how to stop them and my poor hen is getting pecked to bits. What can I do? I would really appreciate some advice at all. They live in a large pen with coop (lot of foxes in the area so cannot free range).
