It sounds like Wry Neck to me. It's a common disease, I've delt with two cases of it before. The symptoms are swaying/tilting head (most often to the right side), darting eyes, poor balance. I highly recommend you take a look at this link... http://www.barbibrownsbunnies.com/ecuniculi.htm

I've had many fellow breeders/rabbit owners use this treatment with sucess. Let me know if you have any questions.
