We are preparing for meat birds in the spring and thinking about our processing ability. When I was growing up, my grandmother would just chop the chickens' heads off on a block and go from there. Now it seems using a kill cone and slitting their throats is the most popular method of slaughter. I understand that slitting the throats keeps the heart pumping longer and therefore they drain more easily. Other than this, why not just chop off their heads? I mean, is there really something wrong or bad about the decapitation method of slaughter?
