So on top of the aspen on their hot spot reads at around 85 degrees usually. We have the heat set to 90. It only reaches 85 on the top of the aspen, and can get up to 95 way down underneath the aspen! The probe is in a cage with aspen, just like the hatchlings. Isn't this an issue? What would you recommend to do? Obviously I want the top to be a good 89 degrees, but if they burrow I'm concerned.

I would like to say most of the time they're wedged BEHIND their hides and not actually in them. They push the aspen around which makes the door to the hides obstructed and will make the hides sit at awkward angles where it looks like they can't get in unless they burrow from under and up into it.. Unless I fix the hides multiple times a day then I usually just see them behind the hides. I just looked now and half are in their hides (An hour ago I just adjusted their cages so that aspen wasn't obstructing).

We also rubbed the pinkies on a warmed F/T adult mouse that we had in hopes of the smell helping.
