i havent read the entire thread, and i dont breed snakes, so idk if its worth anyones time to read wut I think, BUT:

i definately agree it's case by case. depending on how severe the "deformation" or "flaw" is, if its suffering, or if it cant eat on its own, or cant move, then put it down.

also, if I was breeding snakes, i would probably do EVERYTHING in my power to keep my babies alive, bc if YOU yourself put your hard work, dedication, time, and sweat into raising those adults to breed, praying for fertilized eggs, incubating those eggs, monitoring them closely, then awaiting that adorable little BP head to poke its head at you and greet u, rite there, uve gotten attached to the animal and u WILL do wut u need to in order to save it.
