Ball Python Shed - help!

[fluteplanx]

Within the last month or so I have acquired a baby ball python, who is about 5 months old. He has been eating well and seems quite healthy. Immediately before I got him he shed, and the girl who had him before me showed me his shed, which was very nice. In the past week or so, he went through his shed cycle (pink belly, eyes got milky, cleared up), and then I was lucky enough to come in here to see him in the process of shedding yesterday evening. He had his entire head done (eye caps and all), but his lower jaw appeared to still be intact. In trying to pull the skin farther back down his body, he ripped off "the head" part. After about 15 hours, he's proceeded no further. The skin needing to be shed under his jaw appears to be wedged in the slit between his jaw bones. So this morning he had peed in his tank, so when I removed him to clean it, I put him in a rubbermaid box (shoebox sized) with about 80 degree water for about 45 minutes. When I took him out, the little edges of skin on the top of his body, just behind his head were definitely easier to move around, but as I used a wet towel to try to slide them back, they still seemed to be stuck, and I've made no progress with the lower jaw area. To me it appears that if he can get the lower jaw part started, he will shed in all one piece. But as it is now, we're sort of stuck with the lower jaw part staying in place and behind his neck sort of waiting for that piece to catch up.

Any advice on what I should do? Should I wait a day and soak him again? To make the situation harder, he is a little head shy so trying to move around up there isn't easy. The humidity in his tank is always between 50 and 60%, and for the last few days it's been at least 65% My humidity gauge is a dial one, but when I first got it I calibrated it and it was only about 2% points off. Also, can I feed him? It's been almost two weeks since he ate (as I didn't feed him before when his eyes were milky) and I'm sure he's getting hungry.

He does appear to still be "trying" to rub the skin off. Since he's been back in the tank after the soak he's been rubbing around. I do have a rough rock in there for him to use, but he seems to ignore it and try to use his own body instead.

Thoughts? Thanks much!!!
