1. Thanx!
2. Oh no

yes she was wild. Is that a concern? I've read up they can get pregnant by themselves? And need ground to dig in, and if not die? I was really hoping its not a female for that reason. I didn't know as much about them as I've read now, I wouldve known better.
3. What's the black spots? Does she look healthy?
Wild caught chameleons oftentimes come in with parasites, so it is recommended to get a fecal test done to determine if she has any, and what to treat her with.
they cannot get pregnant by themselves, they still need a male. that being said, if she bred before she came in, she could very well lay eggs, and i believe, also lay a retained clutch several months after that. (females can hold sperm in their bodies, and can lay one clutch, then lay another a while later)
They do need dirt/sand to lay their eggs in. a recommended method is to get a 5 gallon bucket, and fill it with at least 12 inches of washed playsand or dirt, that is damp enough to hold a tunnel, and place it in her cage. she will lay eggs if/when shes ready.
females are not hard, just different, do some reserach on this forum, or ask any questions you have, and someone will respond.
as for the black marks, they are scratches/bruises, probably from being climbed on or picked on by other chameleons. in time, as trace said, they will go away with shedding and a good habitat.
