It's a fact that we have all become "townified". We have arrived at such a remove from basic farming and the natural cycle of life and death for farmed animals. Fiona and I are the same.
As a child, our neighbour used to keep one or two pigs for the table. I was taken to a slaughtering once and of course it upset me. But I did have the wit to realise that the pig had enjoyed a good life and its end was quick if noisy.
My mum had a very old-fashioned job pre-marriage back in the 1940s and 50s. She worked for the Dept. of Agriculture as a Poultry Instructor back in the days when every rural smallholding or farm kept poultry for the table or to sell. She had no qualms about grabbing a bird from our flock and dispatching it with a quick neck-twist. Then it was hung from the barn door and plucked.
Even so, I would be hard pressed to do it myself. Then again, if times became tougher, I (we all) probably would do the necessary. I think the balance of caring properly for livestock and treating them humanely at the end is very important. Unfortunately, our supermarket shopping society has distanced us from what happens to the animals that we eat. We treat chickens like vegetables in reality, Shameful. But we all consume the end product without protest.
