The thing is, there are many keepers on here that just repeat what they read. Regardless if it is correct or not they have no experience and cannot elaborate on their post
First off, congrats on the successful mating.
Once the female gets impregnated it will be around 30 days until she lays. Could be more could be less. She may get very unrestful in the later stages going off food and searching the cage for a suitable spot. Or she could just act normal up until the point she wants to lay. A nice large laying bin inside the enclosure may work. It needs to be of a good size. 12x12x12 at least. Fill it up with sand, soil or a mix of both. I like to mix them to 1/3 sand 2/3 sifted topsoil. I get the cheap stuff for like 1.50 a bag and sift it myself. Once she starts digging around she may dig test holes for a day or more. Make sure NOT to let her see you when she is digging. Putting something over the cage so she cannot see you is what most people do. If she does not lay the eggs but is digging test holes for days and it is close or past her term then you may want to try a different approach. You can use a plastic trash bin filled up with your choice of laying medium. Put a light source shinning down in the bin. Do not put any plants or anything in the bin just bare floor. Since she cannot escape it will give her only a few options. Keep digging tests or actually lay. Some females seem to prefer the trash can method. I would suspect its because the laying medium is actually the ground and not raised above ground level like a bin in the cage. After she lays incubate the eggs. I will let Jim do the rest of the talking for that one. Go to chameleoncompany.com and look at the breeding article. It will give you more info on the process and incubation.
Hope this helps a bit
Edit: Do not fill the bin up all the way when inside the cage. This way the dirt doesnt spill and she has what she dug out to pack back in the hole.
