Thanks, Jennifer and Raj.

David, yes, I am housing them in a wire cage that I made and posted about in the caging forum before getting the cresties. I read numerous care sheets ahead of time and there was no consensus on whether it was best to go with high ventilation as with chameleons or with high humidity, so I followed the advice of the best-written care sheets and made a high-ventilation enclosure and mist them 3x daily and use a substrate which retains moisture well (peat moss). So far they seem very happy with the setup.

The entire enclosure is pvc and hardware cloth painted over with rust-o-leum, with newspaper covering the bottom and a cat litter pan filled with peat moss on top of that, then 3 fake plants attached to the back wall and one attached to the ceiling for hiding spots and a half-dozen or so sticks going every which way for them to climb on and reach the bottom with. I'll definitely be keeping an eye out for bad sheds and adjusting husbandry accordingly. However, if I go along with Jessica's suggestion (which I am leaning toward doing), I'll be getting a pair or trio of adults and housing them in this and moving the babies to a spare rubbermaid with spare hardware cloth melted into the top.
