I wanted to include a video of her and can not figure out how! This is one of my 3 year old Langshans. She started doing this off balance stomp walk several months ago and I decided it must be a vitamin deficiencie so I gave her a few days of Poly Vi Sol drops. It seems to do the trick but now she is doing it again and the drops are not as effective. Should I keep giving her a dropper full (half and half with water) every day until it stops or can you give too much of that? OR is it something else?
