If I were interested in breeding chameleons, I'd do research. Among the top things you'd discover, doing the most basic search, is 1) don't support big chain stores by purchasing/"rescuing" a chameleon from them and 2) how to determine the gender of the species I wanted to keep.
I consider breeding veileds a lot like breeding puppies. Are there instances where it's a good thing, sure, but veileds have saturated the market, making them cheap, meaning the average, uneducated, and poorly equipped buyer can acquire and subject the animals to a miserable life. If I were to breed veileds, I'd focus on premium bloodlines, with better colors, higher casques, and not breed chain store animals, that may be line bred, are average at best, aren't being cared for properly, and worst of all, encourages them to continue to offer animals they have no business offering, since they do not provide the proper care the animals require.
What doesn one do with a bunch of animals they breed, in a market already saturated with them? The prospect of the animals finding their way to capable homes drops dramatically.
Breeding any egg laying species and even not breeding them, often leads to death and debility in captive females and shouldn't be taken lightly. I never understand the people that start with a Petsmart animal or female, that also claim they have done their research. If you REALLY researched your options, than at best, you are willing to make poor choices, even once informed and at worst, completely incapable of comprehending basic chameleon care, but most haven't done real research and that's easier to forgive and correct, if someone wants to learn.
Buying veileds from chain stores is like buying puppies from puppy mills or retailers that source from puppy mills. Buying animals from reputable breeders promotes good husbandry, healthy captive population, and contributes to the hobby, while purchasing mass produced, poorly treated animals, of unknown origin and parentage, does the exact opposite.
