Are the hides the right size for him(not to big or too small)?Maybe he needs a lil time to himself. I believe most people recommend 7-14 days of not handling your new snake to let him get used to their new home. Most likely i would take a closer look at the hides as some snakes are very picky about wanting tight fitting hides. You might try different size containers with holes in them to see if he likes that better.Goodluck keep us posted
