He is a six year old RIR and seems to be experiencing paralysis. He will stand if I help him up but can't walk without falling or flailing. He is a wonderful bird and I would appreciate any advice that could help him. I forced him to take some fishoil, avian charge and activated charcoal. I have him isolated and in a crate in jy house. He's lying forward on his chest, with his tail stuck up in the air, his claws are clenched or retracted. He opens his eyes when I speak to him or touch him but mostly seems really wiped out. Please help!!!!
