So the past couple of days have been rough... She unexpectedly had a REALLY bad shed, just pieces everywhere. Even after putting her in a container with wet paper towels for a bit, soaking the substrate and giving her a day to try and slough off the rest, she still had quite a bit left. Had to manually rub and carefully peel off the rest, which of course was mostly her lower neck up to her head. To her credit she only bit me twice during the process.
I was dutifully keeping things humid while she was in blue, but I think what happened was I sprayed everything except the hide she was under (so I didn't disturb her), and she never left that hide so she was bone dry the whole time. That and just before she shed she went up to the highest platform where it's the driest which no doubt didn't help.
