After you resolve the dry skin/shed problem and move snake to a smaller container, I would again try the various methods to induce feeding. Not sure about the effectiveness of "Lizard Maker" but if you have access to any Uta/Urosaurus/Cophosaurus/Callisaurus/Holbrookia/Sceloporus or to introduced geckos, you can offer those frozen/thawed or use those as your scenting source after pink washing. Some people will "assist-feed" or force feed; there are various ways to do this, including "tease-feeding," which some will respond to. Some snakes also respond to live vs. dead pinks, especially in a small, restricted space. Finally, other alterna breeders choose to not fight that battle, but cool the snakes down and give them a shorter-than-normal brumation period. Typically, the feeding response is better on the other end. However, this can only be done if the hatchling has sufficient stores of fat.
Last thought, and not to be viewed as a criticism of you at all, but unless you have experience with alterna, I would never buy a non-feeding hatchling. They often are challenging enough to the long-time breeders, and for those inexperienced in dealing with mexicana-group hatchlings it can be very frustrating.
Good luck.

P.S. Here is a Xmas Mts. hatchling...feeding well!
