I sold some birds to a farmer, who gave me some great advice on chickens and processing. I am just wondering if anyone has the same thoughts. She said she butchers them by opening their beak and inserting a knife into the roof of their mouth, she said there is a spot that you can see, like a small slit, in their mouths that once you push the knife thru it, it kills them instantly. She said the slitting their throats PRIOR to doing this makes for very tough meat.
