Hey Steve, my Big Bertha above had the same thing going on right before she shed today. The skin seemed to be separating in places forming little pockets. I actually started noticing it when she was cloudy. I had never noticed that happen before but then again, she had never shed 4 weeks apart before. She needed a little help this time. She's bloated and due to her condition, it seemed like too much effort for her to get it done on her own.
