It really is a catch 22. Everyone has their own reasons for breeding.... health, target morph, quality of target morph, feeding response, friendliness, and the perfectionist that tries for all of the above and more. It sounds nice to say that all you care about is healthy babies, but how many of you that say that are in the market or even willing to adopt a healthy normal hatchling?
No matter what you breed for, you are going to produce non target animals. The more selective you are, the more non target animals you are going to have. So on one hand it is noble to breed for the best of the best, but on the other, when you do, you have a lot of non target animals on your hands. And of course every breeder here wishes others didn't sell their non targets so they will get a better price for their own non targets. :shrugs: So most cull, in different ways. Killing, selling cheaply, adopting out to good homes. I'm not sure if which of these ways you choose really effects the price of your target animal.
