So I have a 3 month old barred rock. I noticed on both wings in the same spot she has this: It seems to be growing and the middle bump is hard and feels like a bone. Does anyone know what this is? I'm worried about her. She doesn't appear to be in pain. This morning I went out to check on her, and she is doing this thing where she opens her mouth wide, then closes it. It looks like a silent crow or something. Does anyone know what that means?
