Good news on this!

So I think it was sort of a combination of factors of her being near shed and hanging out for a couple of weeks on the cooler side of her tank.

When I moved her hide and the lights came on she immediately discovered the other hides and went to the warm side. 5 days later I fed my other BP and gave her a smaller-than-usual rat pup. This time she responded and ate it!

That was last Thursday, and I took a long weekend off, then this morning found some shed skin in her enclosure before going to work! I'm not sure if it was a full successful shed as it'll be her first in this enclosure (seems weird still to me she took this long to shed since I got her 5/21) and I haven't had a chance to take it/her out to inspect, but this is at least a good sign.
