I keep all my adult cresties in naturalistic terrariums, including my breeders. So far I've had excellent success, I dont use a lay box but eggs are easy to find since they seem to pick out one spot in their enclosure to lay eggs. Once you find the females favourite lay area, it takes 2 seconds to remove the eggs. I've also had 4 cresties hatch in situ, all in all I think naturalistic is the way to go!
