I would go ahead and feed him. If you are feeding live monitor him very closely. If your are feeding f/t and he refuses you can leave overnight at his hide or remove and toss as your preference. If he doesn't want to eat wait until the next feeding cycle or he is done shedding. Should take a couple of days to a week depending on how far along he is. Shedding time varies based on the snake and humidity.

Try to keep his humidity up around 70%
