One of my Buff Ophingtons has a "Hunchback" or whatever you want to call it? I noticed it the other day while out checking on them and just socializing with them, This one is really mellow, comes to you, doesnt run off with the others...ect.... I noticed her head stays to the right and a large lump on the left side.... something I should be worried about or just ignore it and let her be? All are healthy and very active .
