I have two male Pekins that we're raising for food and they're getting pretty big and I'm going to be very particular about how I kill them. I'm already attached to them, big surprise, and I want it to be as quick and painless as possible. How quick do they die if I were to use a killing cone? Do they freak out? I would imagine so. I was thinking maybe just chop their head off with an axe but I'm still not sure. Any help would be greatly appreciated...............Maybe i'll make a duck guillotine.
