After quite a few years of wringing necks, kneeling on geese, and bashing heads I've become really sold on the finisher tools. A buddy of mine has one that he let me borrow and it's quick, easy, and humane, as well as being easy to make a DIY version of. On a related note, we raise and slaughter around 20 meat chickens a year and by far the easiest way to kill them is to put them head down in a killing cone and cut their throat with a sharp knife, the sudden loss of blood pressure has them dead in around 10 seconds and you don't get nearly the amount of flapping around you get when chopping heads off. I have wondered if it would be worth setting something like that up if you had a permanent blind?
