I am by no means an expert but most people recommend to feed inside of their enclosures or they could associate being removed with feeding. My main point to posting was to make sure there is a thermostat connected to the heat pad. Recently saw some pictures of a burnt snake and it was not pretty. Also, does she seem stressed when not being handled? If you've been handling 3-4 a week since the day you brought her home maybe she hasn't had the opportunity fully relax and acclimate. I would personally leave her be, feed an appropriate sized meal once a week (10-15%) of body weight for several weeks and don't handle at all. Maybe try to work with her again after about a month. Again, this comes from my short experience and a ton of research. Again, hopefully someone with some more experience can chime in. Make sure the hides are an appropriate size as well.
