I'm getting a bit lost here.
I never considered livestock as pets

Keep them and eat them or what they produce, otherwise - what's the point?
Hands up - I never ate my goldfish, hamster, guinea pig or dog. I really wouldn't want to have to stretch a hens neck sharp enough to kill it but have had to smack a fish out of it's misery on a stone wall after a feckless son landed it by mistake. Other people can do that far better than me
