Hi Shelton, I have never bred them myself but Rick who used to use the forum did, if i can remember rightly he incubated them at low temps i.e. 24c and they hatched after about 6 months or just before that, have a look on the melleri discovery sight
The Melleri Discovery its an invaluable source of info, hope that helps.

Hi Karen,
I was wondering if you have any experience with Meller's chameleons? I have had a trio of 2 females and 1 male over the past year and was hoping to breed them. I have had them in a large free-roaming setup and have managed to hopefully have a successful mating. One of my females laid 81 healthy looking eggs yesterday and I was wondering if you knew the best incubation techniques etc. I have read all the available info that I could find but there is generally little published info about. Any first hand experience would be greatly appreciated.
