We do not have any of those things.. he won't eat out of my hand anymore because he's really scared right now. It really seems like it is something neurological, though. He seems really out of touch with his right leg, can put pressure on it but falls over when he tries to walk. My mom is a nurse and doesn't think gout could cause him to act like this. I'm just such at a loss .. She also says if we gave him vitamins that for it to even be effective, we'd have to give it to him over a looonnggg period of time. I trust what you say over her because you know more about chickens, just thought I'd let you know, though.
I have since put ACV into his water bowl because I think he is still drinking.
