Is this normal?

[sneak]

I received my baby BRB almost two weeks ago, and I have here in a rubbermaid shoebox. Temp is 80 degrees, and the humidity is at 90. She is always hiding in her box. I never see her. She is never in her water bowl or anything. She's eating great. She was a bit nippy when I first got her, but she's been a sweetheart ever since. I was just wandering if this is normal behavior for a BRB. Thanks.
