Yeah, she's a big chunky girl ! If she eats supers every day you can cut it down to every other day so she doesn't gain any more weight. Give her plenty of greens though. If the basking temp. is 107, cut it down to 100.....very few adult dragons like it over 100. She may be hiding because it's too hot. Her tank is very nice,but I will suggest that you replace the platform/cave with a nice basking log. Beardies love to climb + cling on to things, and that keeps their muscles toned better as well. At least get a nice thick branch to go from about half way across the cage to the platform and see if she prefers that, and if you don't get rid of the platform then definitely block the hole to keep her out. I think she;ll bask more + be a bit more active if you add a climbing log + close up the cave.
