Shed is good. Only growing snakes will go into shed as a general rule. Eastern Blacknecks have a reputation for being fussy eaters, especially when they are very young and/or have recently been moved to unfamiliar surroundings or are otherwise stressed due to any one or a few of a myriad of reasons. They are just not good "beginner" snakes generally speaking.

If he is active and moving about the enclosure after he sheds, give him a day or two after shed and offer food again. A good time to do this is in their mid-morning very shortly after they have warmed up fully. Another good time is late in the day, close to "lights out" but make sure it is very low light intensity, like it would be at sundown. If he doesn't eat, don't offer him food again for at least a week of very dry "weather" Sometimes it helps non-feeding eastern blacknecks if you withhold water for a few days, do not offer food more than once a week, and keep the humidity very low. Follow up by a good heavy misting that should suddenly increases humidity briefly. Sometimes they get a bit parched after the fast and lack of water, and come out because of the sudden humidity increase and will then snap up food for it's water content.

Good luck and keep us posted. Let's hear how he is doing, good or bad.
