I noticed that my 23-24 week old is having some problems "moving around". He walks fine, but kind of leans back on his "hocks" I guess and then relaxes down. I've never seen a chicken sit down like that. Then he relaxes for a little bit and can run around again, he kind of walks on his tip toes though. He doesn't have any obvious injuries that I can see, except that maybe his legs are a little "close together" and all of his joints on one foot are swollen. The only think I can think of is arthritis, but I don't know how likely that is in such a young bird. Does anyone think that it's arthritis, or any ideas about what I can do to make him more comfortable? Thanks everybody!~Ms. B
