I have a male normal right at 2500 grams that will.not.eat if he doesn't have a hide. He's in a 41 qt rack and stuffs himself under one of the Reptile Basics large plastic hides.
I would also contact the seller and ask exactly how your girl was kept: tub type and size, temperatures, substrate, what time of day she was normally fed, was she on live or f/t, was she eating ASF, rats, or mice, etc.
