Hello, and to BP.net...

The first thing is, have you left her alone since you got her with no handling to let her acclimate to her new surroundings? What type/size of enclosure are you keeping her in? What type of heating are you using? What are you using to control it? What are you temperatures and what are you using to measure them? And what type of hides are you using?
The first thing is to make sure there are no husbandry or security issues. If you could post a photo or provide the details of the set-up, it would help. Also, what type of prey have you offered, and how often?...
