I’ve got a hen who seems to have injured hocks. She cannot walk but a few steps and balances herself with a wing. the roosters have piled on her multi able times the past month which I think contributed to her injury. I’ve kept her separated in her own large area of the coop along with a older hen that also gets jumped on by the young roosters. They are happier but she has not made any recovery. Suggestions? I have about 7 roosters to 20 hens. Only three hens are young.
