I have a hen that has always been lowest in the pecking order. It has gotten worse to the point that everyone is now ganging up on her and jumping on her to peck at her. She hears anyone coming and starts freaking out and running away. I think they go after her bc she is so scared. Has anyone tried medicating to help with bullying? I was thinking if I gave her prozac and she wasn't acting like that, maybe it would get better.
