If you read the link I gave you there is a description of the size of container I put in egglaying females' cages...and what I do after they start to dig in these containers that are sometimes to small for them to actually lay their eggs in. These small containers I leave in the cage are meant to give the female a place to dig to indicate that she is ready to lay eggs (although some species will lay their eggs in the small ones) before I move the female to the egglaying bin I described.
Like many species of chameleon, when a receptive female meets a male they will mate....so breeding a receptive pair could be considered easy. If the female isn't receptive (or already is gravid) she will turn dark and hiss and sway and show all the signs of being non-receptive/gravid. If the male comes close enough she will likely attack him.
Once they have mated and the female is gravid, she will begin to repel the male by her colors and actions...and his presence in the cage will stress her out.
During the time between becoming gravid and laying the eggs the chameleon will need to be well looked after so that she will be strong enough to lay the eggs and so that they eggs will be healthy too.
Once she is gravid, you still have to get through the egglaying...which is NOT as easy as getting them to mate. The female needs what SHE considers to be a suitable place to lay them. She has to be healthy enough to lay them.
If you get through that, you still have to incubate the eggs in a suitable fashion that they will get what they need to survive to the point of hatching.
You said in a separate thread that the male was staying in one area of the cage and the female in another....she is likely "stuck" there...if she moves the male will see her so to stay out of the male's sight/attention she has to stay there. If you keep her under that type of constant stress, her immune system will drop and she could die.
You said they were 5 - 8 inches long....snout to vent or snout to tail tip??
What color is the female showing?
