In my opinion, I would rather unwanted snakes be fed to other snakes as opposed to being neglected or abused. Some snakes are just naturally built to eat other snakes, and so long as the food snakes are treated humanely and euthed humanely if they're not being fed live, I see no problem with it.
If I ever ended up breeding snakes and ended up with normals though, I would probably end up keeping them forever unless I could find them good homes, simply due to personal attachment to them. I would be a terrible farmer or feeder breeder for the same reason.![]()
