Pekin duck with Wry Neck!!!
One of our Silkies had this same problem. We gave her vitamin water/electrolyte water. I also was putting Vitamin E in her food daily. It took about two weeks for her to totally recover. I had read to crush Vitamin E and cook it in an egg to feed it her. I wasn't able to do that, I couldn't bear to feed her sisters eggs :) It would be like having her eat her niece or nephew :)
