>> should he destroy the entire litter because on this one animal?
just to clarify what I meant earlier, if it was a birth defect and I (as in, I - the breeder) would not be able to keep it or find it a good pet only home, then I would cull the defected one. If the defect was something that popped up in multiple babies within the same litter or subsequent litters, I would consider culling them all and not repeating that particular breeding. If it was something that happened after birth, like an injury, then the boa itself and genes are fine and I would not cull.
My ex has a pet-only one eyed sunglow boa and I have a boa that had a prior injury. The sunglow will never be bred but I will try to breed the other one as long as the vet gives me the all clear that it won't do her any harm to try.
Just throwing my $0.02 out there.
