You had two chameleons of different sexes together... and you're surprised they're mating and going to lay eggs?
Well, if you don't want this to continue happening, and if you don't want eggs, separate them now so they do not continue to lay clutches of eggs. You should invest in a cage for one of them anyway because two adult chameleons will not fit in a single cage (unless we're talking about a huge cage, but I'm guessing it's a 2 x 2 x 4?) Secondly, read all you can about females laying eggs - there are great books and loooooads of good threads on the forum about it. You're going to need to make sure her calcium intake is good and that she has a bucket or something to lay her eggs in. There should be plenty of information about it if you search the forum.
If you do not want to incubate the eggs, which I imagine you don't, just throw them out. Incubating the eggs would take close to 8-9 months to do and would require the cost of an incubator, along with the costs of feeding and housing 20-30 baby chameleons as you grow them up to 3 months and find them good homes.
Hope that helps a little, I'm a little bit in a rush.
