Be careful that they don't stay constantly damp. Personally I keep them on dry paper towels and use a 16 or 20 oz plastic bottle cap for a water dish so they don't get the enclosure all wet.

You should keep them damp for a day or two but not much longer than that. If I'm keeping them in a plastic shoebox tub, I set just end of it (opposite of the water dish side) on an undertank heater and make sure there's plenty of holes smaller than their heads. Good ventilation is important.

Stay on top of it and keep the enclosure clean. This means daily cleaning for a group of them. Too much moisture and/or dirtiness can cause blister disease really fast.

You don't have to worry about feeding right now. They just got well fed on yolk. That should last them a while. Just make sure they're dry after the first day or two, and always have easy access to clean water.

Good luck, and congrats!
