I have seen similar issues with some of my hatchlings. I keep moist paper towels in the tub along with a hiding spot. I use an upside down plastic bowl with a hole drilled in it just big enough for them to fit through. When they refuse to eat for several weeks, i start assist feeding them prekilled pinky mice weekly. I always offer them a live crawler mouse first, then if they wont take it, i would assist feed them a prekilled pinky. Sometimes it takes several months of this routine to get them eating regularly. I would worry more about the not eating part than i would his shed issue.
Here are the biggest keys to remember:
1. Make sure he has the proper temperature. For new hatchlings, I use 85 degrees F for ambient temps and 95 degrees F for the belly heat.
2. Give him a hide box and don't mess with him except the once / week feeding attemps. Leave him completely alone until he starts eating regularly. Remember, force / assist feeding is very stressful on you and the snake.
3. Make sure his enclosure is the correct size. The correct size for an enclosure for a new hatchling is a shoe box size container. Bigger is not better.
4. Keep the humidity up (60% is what i recommend). Use damp, not wet, paper towels in his tray / tub.
5. Always have clean fresh water in his enclosure.
6. Be patient and keep a close eye on his appearance. If he gets thin or his skin starts to wrinkle, he is probably dehydrated and you should take him to a vet that specalizes in snakes. You don't want to lose him.
Hope this helps and good luck.
