Tube feeding is what I would do, but only after her hydration was corrected. Never tube feed a cold or dehydrated bird, it can kill them.
Rthepunk, check out the tubing link in my sig, then go find the supplies needed and I'll teach you how on the phone or here, whatever is easiest for you...
She needs to be kept warm and she needs fluids, lot of them. Get her warm, then hydrate. Once she is warm and hydrated you can worry about food.
