I got a 8 ish month old roo that was fine up untill a week or so ago. He almost acts like he has a neurological problem. He stumbles around when trying to move fast. He trys to stick with the rest, is semi interested in food, but sits around like he is cold. Haven't seen poo, and his butt is clean. I don't see any wounds and all his joints feel in tact to me. He is SOO thin when I picked him up and hardly any crop to speak of. All the other birds are fat, happy and running around like nuts. What should I do for him??
