Oh and KEEP HIS WARM. Take a bottle, 1 liter or something and fill it up with warm water and put a towel over it. Let him curl up in the towel. It will mimic the cramped space that the nest would be. But be careful, as the bottle of water cools, it will pull heat FROM him. You can also use a heating pad but if you do, put it under the box and give him an area to get away from it.
We will want to bury himself in some towels...
