Eep, doesn't sound good. Keep an eye on him, and if he hasn't started moving/drinking tomorrow I would call a vet or the breeder/store where you gut him. It sounds like he's a bit stressed. (Which is understandable, he's had a big day!)

The skittishness doesn't really concern me because that's fairly normal, but inactivity for a long period of time like that and the lack of pooping is NOT.
