Yeah i have a big bin at the bottom of her cage, its almost 2 feet deep and probably about 2 feet in circumference filled almost to the top with moist dirt! !!
Chameleoman, please do not breed your female until she is over a year old. The eggs will take away the calcium that your female still needs to grow and become an adult. As kinyonga said above you both need to get a laying bin in for your females. You might find my attached egg laying/laying bin blog helpful. https://www.chameleonforums.com/blogs/jannb/345-egg-laying-laying-bin.html
