Bite Me! It's ok
First, it isn't "genocide" as he isn't killing off the entire species, just the hatchlings that do not fit his qualifications. It has just been bad luck that none in those particular clutches met his requirements.
If a breeder is selectively breeding for temperament and for food preference, culling those that don't fit those qualifications is what needs to be done. When first produced, bloodreds (I'm pretty sure it was the bloodreds, but may have been another morph) were known for being lizard eaters and refusing pinkies. It took years of selective breeding and outcrossing to produce hatchlings that would readily eat pinkies out of the egg.
I am sure there are many breeders of all snake species, that are selectively breeding for the above mentioned traits. I know I would prefer to keep those that were easier to handle and that ate pinkies right out of the egg.
And what about those hatchlings that won't eat anything offered? Is it wrong to cull them (euthanize, if you prefer) or would you rather let them suffer and starve to death? What about other deformities? Was it wrong to cull this hatchling?
"But there's a difference between physical deformities and behavior/temperament/food preference/etc." Look at it this way, if man didn't selectively breed for ALL desirable qualities, we wouldn't have ANY domestic animals. There would be no dogs as they would all still be wolves, horses would be wild, pigs would still be wild boar, cattle would still be wild, sheep, goats, fowl of all kinds, etc would all still be as their wild predecessors and we would still be hunter-gatherers.
No one is forcing you to cull anything you produce, but don't knock those that are trying to improve the cb specimens.
I understand what you are saying but killing nearly 100% for several years for doing what comes natural to them? Something sounds very wrong with that. I understand culling problem animals to strengthen the bloodline, but I'm afraid he is setting his bar way too high. Ask any Gray Banded breeder and they will tell you most want to eat lizards, but can be switched to pinkies without a lot of effort. Cal Kings also are full of spunk as I mentioned before. If the snakes were kinked or had some other deformity, fine. But those snakes were being exactly as they should have been. Sorry 100%, for several years? That's like killing puppies because they peee on the floor. It's their nature to do that! Patience and proper husbandry will fix those problems.
