Personally I would rather quit breeding all together than cull healthy animals simply because they are as you called them “ugly” ……….but again that might be just me
There is a difference between breeding for food and doing what you are doing. You are using the breeding for food as a justification, if that make you feel better about it, good for you but what you do is not breeding for food, you are breeding and disposing of what you consider not being worth your time.
And I will add you can do whatever YOU want I am not hear to tell people what they should do with THEIR animals howeer personnally I would never support someone who does this which means no business from me.
