WC v. CH/CB
Hi, Chris.
You will notice that in the pictures of Mellers, that those that are WC, almost always have a broken horn. Most are broken during shipping to the states.
On the other hand, you will see a number of CH/CB in chameleon forums that have a full or developed horn. Better care and shipping prevented the horn from being damaged, and the recent supply of CH Mellers, was of baby Mellers before they had a horn, now of course they are getting big and you can see the development.
Once the horn is broken, they do not sadly grow back. Kind of like a Rhino.
