are they sharing a cage? at the size of the male, they need to be in seperate cages. its okay for babies to share cages when they are pretty young but he is a lot larger then her. sharing a cage at this age will cause serious stress on both of them, one will become dominant and can injure the other as well as take all of the food. its highly recommended to have them in seperate cages from at least 3 months on as chameleons are highly territorial!
also, they are both gorgeous! congrats on your new friends!!
