Mix her feed to a mushy paste with water and mix the vitamins into it. That way she will be getting enough fluids without needing to drink and they usually enjoy a wet mash like that. Have you tried some scrambled egg as a treat or meaty cat food or slivers of raw liver are full of good nutrients. Only give her moist foods and make sure she has a source of grit available if you are giving her anything that needs grinding up.
I'm afraid my guess would be that she has Marek's as one or two others have suggested but it doesn't mean she won't recover from this attack. Unfortunately if it is Marek's she will always have the virus and be prone to other outbreaks at times of stress. Silkies are unfortunately one of the most vulnerable breeds to this disease.
