Ive got a roo whos maybe a year old. Hes been fine and i noticed 2 days ago he wasnt standing tall like he normally does. Today during a photo shoot i picked him up and he smells bad. like rotting flesh. Under close look the feathers are nasty and falling out on his back. I didnt notice because he looks fine until you move the top layer. The skin is black/brown and is hard if you tap it. Smells horrible and there is no sign of any injury. Never seen it and would like to know if i need to kill him.
