I'll be doing it on a farm for crying out loud.
My friend owns a farm, he employs a farmer to rear animals and grow crops. It's not like I am just going to find a random lamb in the wild and kill it.
I've actually helped do this with a pig once, quite some time ago when I was staying with an indigenous tribe in Costa Rica about 10 years ago.
One of them where the women all have their nips out?
