Confused with one of my expo girls.

I picked up 4 girls at the Sept. Anaheim expo. One was a 400 gram albino. The past week or so I have been finding her in her water dish every night. She doesn't have Mites, I allready checked and it would be pretty easy to tell since she is an albino. she is in a animal plastics rack with a helix. It is 88-89 at the rear of the tub and 79-81 in the front. humidity is fine 60% give or take. She is always in her hide. if she ever comes out of her hide she is in her water dish. I have no clue. I have 3 other girls in the same rack because they are in quarantine and they are fine. I have 15 snakes and have never seen this.

I bet she is going into shed. its hard to tell when albino BPs go into blue.
