From the pictures I'm not 100% sure but I don't see a spur on the back of the chameleon's foot. Also, the colors and crest look a lot like the females usually do. I'm quite sure that it's a female unless the spurs are out of view in the pictures.
By the way, I think she has really great colors and your terrarium looks great. Having a female can be more difficult because you have to more precisely regulate their feeding and take steps to avoid egg binding but they typically have much friendlier personalities.
Oh bother... Especially when I thought I had a male chameleon...
What are requirements for females that are different than for males?
Can a female be kept in a cage with a male permanently? I am interested in breeding my chameleon(whatever sex it turns out to be) but very unsure about how people house the chameleons that they are breading.
I don't have a female so I'm a little rusty on their requirements but the big problem you want to avoid is eggbinding. If you overfeed the chameleon they produce bigger clutches. As I understand they lay clutches of around 20 in nature but can lay 10 times as many eggs in captivity. This presents a problem, though, because it's a larger number of eggs with a higher chance of becoming impacted.
The key is to make sure you have sand for her to bury her eggs (even unfertilized ones) in available at the right times. I'm sure others will be able to give you better advice than me, though!
You'll need to keep this chameleon separate from her mate. Most chameleons (including veileds) need to be housed separately. They should only be briefly introduced for their breeding period and then separated again. Even seeing another chameleon causes them stress which can be detrimental to their health. So, there's some bad news...
Good news is, though, the females stay smaller and don't need as large of habitats as males!
Don't be too disappointed, our first was a female and she is a sweetheart, except when it comes close to her laying time.
Jannb has great tips about egg laying and all it entails. She has quite the experience with veilds and has helped me with my girl as well.
Also, chameleons should not be housed together at all. I've heard of two females together in a large enough cage though. Still, it is not recommended. When mating them, it is only temporary.
