I adopted Romeo about one month ago from a breeder . She claimed that her other roosters were picking on him and wanted to rehouse him since he was such a sweet boy. Not sure how old he is. He started out with very stiff legs but got around pretty good. Now after five days of limping around he can't put any weight on one leg. He's hobbling a few steps and laying down. I carry him at times when I see him struggling. No apparent break in leg, he doesn't flinch on examination. How can I help him?
