It's been going on for a couple of months now I see it going on a couple times a week, there not pecking at each other, the one on top was getting pecking at in the past which is why she has a shield on her back but I've seen it where she will be standing there and the other one will purposely...
So I have two hens and I've never seen anything like this before they are Eastereggers and one of them likes to be sat on its always the same two does anyone know why it's happening?
