I have a rooster who is five or six months old. He has always been a little off. He was extremely slow to feather and I presumed due to a slow feathering gene. He does not crow, he is extremely skittish although that has been improving a lot in the last month. He has always been very particular about how he is held and if you hold him wrong he will nip you but has never done anything else hat could be seen as aggressive. He is accepted by the flock and has some close friends within that group that he spends the day with. Last night when we were putting our birds to bed my husband noticed something he thought was a lump on Gwen. We handle each of our birds daily as we bring them to the runs under our big trees and then carry them to bed at night and we have not noticed this dramatic deformity in the past. He has always seemed to have an odd/contorted body shape but nothing like looking like a humpback. My first thought was a tumor but upon palpation I can feel only bone structure. His legs have full range of motion. His gait is a bit off and his wings are not lateral. He seems to always be leaning. His eyes look bright, alert and healthy. His appetite is normal and he is exhibiting normal behaviour a such as dust bathing, scratching, foraging and socialization. I am unsure of his breed. Due to his muffs I have presumed an EE. We got him with 9 other chickens of various breeds/mixes at the Oregon Poultry Swap spring event this April. He is not from a hatchery, was hatched in a home incubator from the sellers flock. The abnormality is on his right side near his hips, I think it's slightly above his hip. I wondered if he had dislocated his leg but he is walking. Here are some pictures I took last night: Any help, thoughts will be greatly appreciated. We do not want to cull him, just give him the best life possible, so looking for ideas on treating or caring for his condition.
