What's the temperature in her cage? Do you have a thermometer? And do you have a heating set up? You did exactly what you should to get her out of the attempt, so good job!
Now that she's warmed up, though, you need to keep an eye on her for the next week or two, and make sure the temperature is warm enough, or possibly bumped up another degree or two. Make sure she's also getting 12-14 hours of light during the day time, and that there's no drafts near her cage that could have caused it.
Another thing to keep an eye out for in the next couple of weeks is any signs of sneezing, sniffling more than usual, a runny nose, or raspy breathing. Those are all signs of a URI, which can be caused by hibernation attempts sometimes. If you see anything like that, she needs to go in to the vet ASAP, as URIs turn into pneumonia without antibiotics.
