I think that the shed cycle is triggered by something (chemicals in their brain???) Don't know for sure, but I do know that once they are finished with that cycle then they are done. The skin that is on is just the skin that is on.

Sometimes when they snakes haven't been cared for well (as might have been the case with this guy before you rescued him) they will do a couple of incomplete sheds before a perfect one.

There are methods that can help with incomplete sheds: soaking and then running the snake through a washcloth, for instance. You just need to make certain that there is no old skin that is encircling any part of Chance's body, as this can cut off circulation (as the skin continues to dry) and cause a dangerous situation.

It sounds like he is trying to hydrate- maybe because the skin is itchy?? Try the soak method- here is a sticky explaining it: http://www.ball-pythons.net/forums/s...ad.php?t=28794 and here's a cool link: http://www.ball-pythons.net/forums/s...hlight=ecdysis

However, leaving humidity very high can lead to RI. If the substrate is too wet, this could lead to scale rot. I still suggest that you bring the humidity down and try to help him with the old skin. All else fails, keep a close eye on him for when he goes into blue next time and bump the humidity to 60%~ that is all that is needed for a perfect shed
