Ok, raise the humidity up higher, i keep mine at around 50-60 when they arent in shed, when they are in shed i raise it up to about 80, no less than 75 at least.

As far as how long it will take ........its hard to say exactly, my corns eyes turn blue and then a few days later she sheds, but with Roxy, it usually takes about a week or so.I think its differnt with every snake.

Hope that helps
