She might be a bit big because of the 3-4day thing I mentioned and not 7 days. How often are you holding her? Might be over doing it possibly. Have you got a digital or analogue hygrometer? I would personally try the feeding box if you cannot find issue with the others. As previous message you might want to change back, but before doing that maybe put her old hide in the new vivarium so she has something familiar in there.
