Great choice! Yay!!!
I have 2 females and they are my first and only chams so far. I didn’t really chose to have females...they just kind of happened. While I absolutely adore my beautiful and chronically grumpy ladies, the whole egg-laying thing provokes severe anxiety. Even though one has successfully laid once with no problem and I’m pretty confidant in their husbandry, it is still nerve wracking. For this reason alone, I would recommend getting a male. Males are also more colorful and have that gorgeous big casque. So, male gets my vote.
She is very sweet. She's been getting comfortable and stretching out in her enclosure.
Females can have a little calmer attitude then males -- though this is not always the case. IMHO the egg-laying is not hard if you are set up properly and have your husbandry on point. I carefully sifted coco fiber to make Mona's lay bin and she choose the potted plant on the side of her enclosure instead. My understanding is a good amount of egg binding happens when the eggs do not form right inside the chameleon. Both my girls are chill and very sweet. That being said, I would still like to have a male at some point for the experience and the coloring.
If your husbandry is on point and you're prepared for any complications that may arise, there are no problems with having females. I have 2 girls of my own. Males do tend to be more forgiving if something isn't quite right, but chams in general are pretty demanding reptiles.
