OH...and one more thought occurs to me...quarantine the heck out of her if you do end up bringing her home. Keep her in a separate room, as far from the rest of your collection as possible. And have a completely different set of equipment for working with her that never touches your other animals. Work with your established collection first...wash...then work with the new comer, then wash wash wash. If she IS sick, you don't want it spreading to your other snakes.
