Stop moving her to feed. It causes unnecessary stress. Offer prey even if she is in her hide. If they don't come out leave it just outside the hide entrance overnight and they know its there. From the pics I can't say for sure. It's easiest with video but it does look female. But at that age it doesn't really matter cuz they will always be hungry cuz they grow fast when young. Relax, wait for her to shed and try again.
