When DC were small they went on a farm activity holiday and learned to milk goats, make butter and gather eggs. As a child during the war we kept chickens and I can remember when I was 3 or 4 one of them being killed for Christmas. My mother tried to keep me out of the way fearing it would distress me but I found my way into the shed to at least see the plucking and cleaning, even if I missed the kill. I was unbothered by the experience . Many years later one of DH's aunts, a farmer's wife, brought round a rabbit her husband had shot and showed me how to skin and eviscerate it ready for cooking.
We always felt, as a family we had many of the skills we needed to live off the land should it ever been necessary. While I have every respect for vegetarians, they are in a minority it is just the noise they make is out of proportion to their numbers. Rabbit is delicious, I like it stewed and as pate.
