No problems really, some won't eat in shed. Take the rat out and let her shed. Get humidity up to 70. She will go blue, ( yes they can have a hard time seeing while blue), then clear up, then a few days later shed. It will not hurt her to wait until after shed. Then maybe try a p/k rat and take baby steps to f/t. She may need a few live feedings until she is all adjusted to her new home.
