What Do Breeders Do with Bad-Tempered Snakes?

[SerpentineDream]

I've been wondering what breeders do when you get a hatchling--or acquire an adult--that just has an unusually rotten temperament (some species are just mean... that's not what I'm referring to though). It tries to bite your face off at every opportunity. It's the one you dread handling.

I would assume if it's an adult that you bought sight unseen you wouldn't breed it lest it pass on the bad temperament, right? Would you try to return it to the seller, particularly if you dropped a lot of money on it?

If it's a hatchling, do you wait to see if it simmers down before you sell it? Cull it? Sell it cheap, with a disclaimer that it's being discounted because it's a jerk (that would be my inclination)?

I'm interested because I intend to breed for docility as well as health and aesthetics. When I bought my breeders I asked for the mellowest ones in the bunch, all other factors being equal. The idea is to produce animals that are enjoyable for people to work with.... IMO that serves both people and snakes well. But sometimes you just get a bad apple.
