Congrats on the feeding. Just take it slow though, don't rush her meals too much as far as frequency or big jumps in prey size/total volume. She may well need to see the vet at some point but you'll know best from your hands on experience with her about that. I'd likely have a fecal float done though just to be safe. Hopefully you've got her very strictly quarantined from the others.
Poor snake, it's just horrible that people let living creatures end up like this. It's a blessing you've got her and are committed to doing your best to give her a chance to come back to full health. Take lots of pictures so you can look back one day and see how far she's come. :)
