2 weeks old could be reeeallly difficult to sex due to of course the age. If it is a male you have to give it time to see if it will develop the bulge at the base of the tail. But I don’t see it BUT it could show up later on but for right now I don’t see any bulge towards the base of the tail my guess would be female? Maybe another person can help out in this one to the best of their ability but yet again it’s a really young age to sex.
Unless you hatched that chameleon yourself and know for sure that it is two weeks old and unless you have really minute hands, I realy, honestly do not think that your chameleon is on 2 weeks old!
