The main thing with wounds is cleanliness. Keep her on papertowel, change daily. Soak daily with shoulder height warm water (about the same temp you'd give a baby a bath in). Soak her in a sink for about 5 minutes and splash her a little or let the faucet drip to get her drinking (If you have liquid calcium spray you can give her a few drops a day at that time she's drinking water (follow directions).
After she's soaked and drank (and eliminated), empty sink, while she's in it (they enjoy playing in water and learn by watching you), add more water (shoulder height).
At that time add Povidone liquid (Generic brand $12. pharmacy), diluting it with water till it looks like weak tea. Try not to get in her eyes or let her drink (hense the first soak, plus it's important to wash out dirt, but only soak, not rub). Use a cotton ball to gently swab wounds with diluted povidone and let her soak about 5 minutes, gently dry.
You can apply triple antibiotic or bacetracin lightly.
If you keep up with keeping her clean, daily baths and soaks, for about 2 weeks it should heal, providing it isn't too deep or infected.
It's also important to maintain a little higher temps (100-110degrees 10hrs, nighttime 75-80, consistantly as well as giving extra calcium and hydration so she doesn't become lethargic. Dehydration lowers appetite.
My first choice would be to bring her to a vet, but if not possible you may have luck with this treatment. I've used it on many injuries on rescues with good results. I wouldn't ship for a few weeks at least.
Pumping up the weight on the male will also help with daily baths and hydration, getting him to drink. Many people don't realize they need to be taught how to drink out of a bowl. They cannot see standing water. Misting the face and then pouring water slowly into a bowl in front of them after they're warmed up, get's them drinking. Use the reptile calcium spray on him as directed also.
You can't go by how healthy a lizard is by it's belly. You look for fatty pads on the head and hip bones should not be raised. Tail base should be rounded. It's nice to know someone caring if taking over!
Good luck!
