This guy got sick over a month ago. At first just kind of tucking his head down against his shoulders. Then His legs got so weak that he could barely stand. I isolated him, dewormed him, and fed him nytradrench and all the good food he would eat. He never stopped ]eating or drinking but got so bad that he would barely try standing. When he did he'd wobble and catch hkmself with hiS wings then Just sit down. The last two days he's much improved,, standing most of the time but he stands so waddle legged and with his ties not quite straight. Any ideas?
