Rescued Snake: Need some advice

[Capt.Britain]

Doesn't look too bad, I see a little spine but nothing major. I would go easy on food for a bit then go ahead and let her chow down to her heart's desire.

Oh good! I knew she wasn't starving, but I wasn't sure just how bad it was. Like I said in the OP, I've never had to deal with (or seen in-person) anything but a nice, healthy snake.
Currently she's on large mice, which from others seems like smaller than she should be getting. I think I'll feed those out (there are four or five left) and then switch her to the rats.
