So much incorrect information... please just .... don't.
Don't change to a ceramic heat emitter. Chameleons are stimulated by light so go for a spot lamp for basking. They don't need to be situated near a window to be mentally happy. And your chameleon will not kill itself. Move the cage to a happier place? Seriously? I think the experience you allegedly speak from is very VERY limited. Apart from what others have said about a female laying eggs before 9 months age ... she will NOT lay eggs every single month after laying the first clutch! Maybe once every 3 to 4 months if you really push her! But 1 clutch a year/season is natural!
@Cham-Wow please refrain from offering advice from non existent experience.
@Hockey&Lizards you really haven't done all that much wrong in the care of this chameleon. I believe when a chameleon looks like this it is very close to dying unfortunately. Chameleons are very sensitive creatures and hide their illnesses very well that is why they may look fine the one day and almost dead the next day. I personally think that the way you attempted a bioactive terrarium did not work for the chameleon. The cage looks very wet, and coupled with low temperatures it may have started a respiratory infection. You must have a very effective drainage system in a cage like this. Your chameleon probably would have done better in a cage that is almost all screened, with the same watering schedule, effective drainage and warmer temperatures. It's always a good idea to let a cage completely dry between mistings. I definitely think you overwatered for a cage like that. That misting schedule is something I'd use for my veileds outdoors in the peak of summer in South Africa - which gets really hot.
