bad shed? skin left on back

My BP just went through its first shed with me, but it has skin left on its back after 3 days. The head, tail and belly are clear. I was able to get the humidity up to 75% and he got right into the water bowl when I warmed it up. Should I procede to a soak and rag removal or just let him do it? Can I feed tomorrow on schedule?

Yeah, do the rag thing.
Try feeding him, but don't be surprised if he refuses.

Go ahead and feed, if he soaked in his bowl you should be able to remove the shed with your finger or rag either or :)

Update: He got the rest of the skin off of his back, but there is skin left on his head after all. He ate 2 small adult mice yesterday, but the skin looks like a sock over his head! I don't want too help him with the skin on his head. I'm afraid to hurt him.
