I have grown to accept this as normal with my BCI...........each shed she has gone thru she gets very loose skin around her chin/neck area. She sheds perfect every time and the skin tightens up once she has shed her old skin.
I really hope this helps ease your mind, as I don't think it is humidity related at all. Your humidity levels are any thing but low from what I've read.
I would say enjoy your boas first shed!
