he shouldn't be going into hibernation unless you are keeping him somewhere cold. if he is warm him imediatly by holding him close to you in a warm room.
I don't have much experience with hedgies trying to hibernate and someone else may have a better answer than I do. But I think that if he's awake for some of the night like you say he is then he can't be going into hibernation.
I imagine he's just sleeping so much becuase he's still pretty young (you said 6 months right?) and he's adjusting to a new environment. The stress of adjustment and the stimulation of all the new smells is probably wearing him out a bit.
Also unless you stay up all night and watch him you can't be sure that he goes back to sleep for the night when he goes to sleep at 11pm he might get up again later. He may also sleep more because there isn't that much to do in his cage. Do you have toys in there for him? does he have a wheel? If he's got stuff to keep him busy he might stay up later.
