Hello again Tracey,
Well your temps sound good. There are only a few things I can come up with that would possibly explain scratching or odd behavior. I know that some of the Powersun mvb's were having issues. Mostly I believe it was eye issues though. Here is the thread if you would like to read over it just in case viewtopic.php?f=6&t=105629
Is your beardie only scratching at the glass? Has she been digging at all? Have you felt her belly for eggs, in the case that she could be gravid?
I don't know what else to think other than she just really wants out... LOL
