I must have missed something. What is hatching? Chameleons? Are these the veiled eggs? Anyway congrats on the new babies. If this is the veileds, you can use an aquarium with paper towels or nothing in the bottom and a few small potted plants inside. I also put a piece of manzanita wood in there because it has tiny branches for them. I use a 20gal long aquarium so I can put the heat lamp at one end giving them a chance to get away from it if they choose. Be careful with the heat light, don't make it too hot for them. If you use this method, you will have to move them up to a screened enclosure eventually, this is just to get them started. An important thing to remember is to mist them atleast 2-3 times a day because they can dehydrate quickly at that size and have food items readily available. Also make sure that they have a good flourescent light on them.
