Just because it does not come off in one piece does not mean it's bad or that there is a problem. Humidity could be low or sometimes you just get a snake that can't get it off in one piece. If they dont have anything to help them shed ( such as a hide or the bedding to help pull the shed loose) it tends to come off in multiple pieces. We have some that come off in one piece as pretty as can be then we have the ones that looked like they exploded lmao... Shed every where... Little pieces big pieces lol just a mess. So just keep up with the good humidity and next time he or she is in shed spray once a day in the enclosure. If there is any stuck shed just soak and do the towl thing.
