It is perfectly normal for a hammie to wait until super late at night to come out. One of the forum members recently set up a night vision camera on their hamsters' cages and they found that their hamsters were also active around 03h00am. So your little one is not unusual.

Also, it is very normal for a new hamster to be very skittish, even for weeks after moving in. The only thing that will reduce this is contact with you. The more you handle him the more comfortable he'll become.
