I'm no expert, however let's see how good I am in the meantime.
I would say you have a female panther chamelon on your hands, around 3-6 months old. If you could please fill out the ask for help fourm and post it here that would be great. Also, if you have not already the panther care sheet is an amazing resource to read.
As stated above, female panther, old enough to lay eggs. She needs a lay bin. Please fill out the ask for help form and read over the care sheet and egg laying article. More pictures of your cham and her enclosure would help, as well. If you don’t mind me asking, how did you come into owning a chameleon without knowing the basics of the species and sex?
