How big or how old was she when you got her, and how long is she now, and do you have a current weight, since you are worried about her being thin?
Lots of snakes will just be fussy feeders for no apparent reason. That's nothing to worry about. But if she is actually underweight, then you should worry a little.
If she actually is thin and underweight (and not just growing slow because of her fussy feeding habits) you should consider taking her to a vet and have her examined for internal parasites. I say this knowing full well that she wasn't wild caught, but parasites can come from food too, as pythonis pointed out in an earlier thread. Ideally people who breed rodents for snake food are somewhat ethical and ensure that their rodents aren't exposed to anything that could harbor parasites, but if you aren't the one breeding them, you don't know for sure.
Also, do you only feed one prey item at a time? (I don't exactly blame you with only wanting to thaw out one at a time if she eats less than 50% of the time that you do that) You might want to consider feeding two prey items at a time to maximize her weight gain when she does actually want to eat... but only if the prey items are short enough that she can handle swallowing both and not regurgitating them.
Just some ideas here... I realize I'm a little late on the scene.
I hope this helps.
