Hello everyone! I have a flock of 4 week old chicks of various breeds, and I noticed a few days ago that one of my black bantam frizzle cochin has an unusual growth on his/her right shoulder. There are no feathers on this large lump, it's the same pale colour as the rest of the bird's skin, and its hard and very veiny. I cant tell if it's a tumor or something else. The chick seems healthy. It's bigger and has more feathering than my other frizzle chick, but they are both straight run and I have no clue if they are male/female, which I think might be a factor. What do you guys think?
