Precisely. Most young snakes are skittish, especially after being in a show all day and lugged around. Leave him alone in his new enclosure for at least a week without doing anything but spot cleanings and water changes. Then feed him but don't handle him. Once he's feeding consistently, THEN you can start holding him and getting him used to you.

Hopefully he won't be one of those rare stubborn snakes that hates being handled...like my Het Albino male. At least I have plenty of other snakes that love being held to make up for him and any new ones I have to leave alone (spider female currently).
