Sorry about your silkie. The others have given very good advice on the riboflavin (or just use a little crushed B Complex on her food,) and to make sure that she reach her food and water. Injuries are the most common problems with a leg, vitamin deficiency, although it looks more like Mareks or nerve damage because of the paralysis. Silkies seem to be more susceptible to Mareks, but I hope it isn’t that. The sling with food and water in front of her can help if she starts having trouble getting enough to eat and drink. Just let her out of it frequently to give a rest.
