Goose Spasms

So I have a goose who is shaking, his neck is bent inwards and he is pecking the ground or his chest area. He doesn't seem to have control of himself. Has anyone ever seen this?

I just spoke with someone who’s goose was doing this. The only thing I could think of was a seizure type disorder. You can try adding liquid b vitamins to support the nervous system. If he is pulling feathers from his chest, take a closer look. They will pull feathers from abnormal growths on the skin.
