this reasearch should have been done befor you bred your chameleons in the first place but anyways,
15 to 40 days after mating she will lay her clutch of eggs so put a lay box in there now so she can get rid of those eggs cause if not she might become egg bound and die , so make sure you have a lay box that is big enough to hold her and the dirt she will move to make her tunnel and you cannot bug her when she is laying her eggs or she will think you are out to get her and her eggs and will not dig and possibly die from egg binding
