Yep, I agree on the humidity thing but make sure it is not constant or she may develop rot infections. Give her a moist hide and a dry place.

Mine has a pen out in the yard, and I brush her shell with betadyne when I bring her in, to clean her up from fly eggs and stuff. She drinks water outside, I often hose her pen so she can go poopi. And she has a soak in warm water a couple times a week.

Has lived four years already, so it must be working...
