1500 grams is a decent size.
It can take adult BPs weeks (hatchlings-just days) to adapt to a new enclosure and months to adapt to a new environment (undisturbed-e.g. no handling/excursions). She is active because she is trying to find a place to hide that she will not be bothered. She already escaped once in a new territory...she will move everything around for a few weeks and push to test for exits in another attempt. Transporting her to another location is just additional stress. More is less in this case: no handling until she is comfortable and eating regularly.
Since recently she escaped I would reset the clock and give her another 3 months before I was concerned-roll back food offerings to once every two weeks.
As usual I recommend checking your temps regularly and having a water bowl large enough for her to fully submerge in.
Best of Luck!![]()
