Typically staying together until juveniles up to around 4-5 months is sometimes tolerable for them, but you should be separating them by size, and aggression. The males can begin to show aggression fairly early on causing unneeded stress. There are feisty females as well. We have always kept ours in small groups of around 6 and kept them separated by same size, and completely separated any feisty little guys from the rest. Unfortunately with Veiled's the general view from an uneducated public looking into purchasing a Cham is not going to be willing to pay the price of the Cham plus shipping when they can go to the chain store and by one on sale for $40. And your chain store isn't going to buy from you when corporate is putting in all the orders from a wholesale breeding farm. Breeding reptiles looks fun and easy, even though it is rewarding, it's not going to make you a millionaire for sure. The fact is, our established swimming pool construction business practically covers our losses on our reptile breeding business, and affords me the ability to work with these animals that I love. If it wasn't for our other business's we probable couldn't do what we do.
