I have read here that silkies are more prone to vitamin deficiencies that other breeds. It may be worth a try to give her some vitamin B12 and Vit. E in her food. I have had a hen unable to walk and looked it up here and learned about the vitamin problem. after two weeks my girl was up and walking. don't give the vitamin E everyday for it gets stored in the fat and lasts a little longer. also, a warm bath, they love it and it will help get the blood to her feet. hope she does well.
