Michele,
Here's is what we currently use for our new baby chams. We use plastic sterilite (58 qt from Wal-mart) tubs, we don't use the lids. We paint the top three inches with a teflon product that keeps the crickets and fruit flies from crawling out. We place paper towels on the bottom (for moisture and added humidity after misting), small ivy plants in pots, and lots of little branches for the chams to walk walk on. We use 2 to 4 tubs, depending on clutch size. More may be needed for early separation of babies do to size or aggressiveness. We use 4 foot fluorescent 5.0 repti-sun tubes for UVB and a 40 watt house bulb for heat. One fixture goes over two tubs. We have found that using tubs rather than screened enclosures makes it easy for the babies to find their food and easier for us to keep a close eye on their behavior. Also ease of cleaning and controling their enviroment. We place tooth picks in pots with small pieces of fruit for the insects to eat on and also a good place fore the chams to find their food. Also keeps crickets from chewing on chams by giving them a food sourse also.
Hope this helps,
Yosemite
