None of my other hens have a bare patch like this and i dont see any of them picking on her. There are no lice or mites. What would cause this? Its on her lower back right before her tail feathers. There is no blood or scabbing/ Will her feathers grow back? I like those cute short feathers that stick up before their tails.
