That shell is amazing! I haven't seen one that color. Gorgeous!!You can try a misting system. Mister hose hanging above her. It's probably happening in the winter when you bring her in. All you can do is use closed humid chamber in the house in winter. It doesn't hurt her unless you let it get extreme. Right now it's just aesthetic. Being top heavy can be a hazard though. Make sure there aren't any tipping hazards in her outside enclosure since she'll have a harder time righting herself if she flips...mine is pyramided (when I got him in Ohio)and he can't right himself at all.
