So I finally have processed some of my own birds. I went to a class and it was very helpful. I have processed seven of my own birds. It went OK, but I seem to be having difficulty cutting the artery. I am using a killing cone. When I processed my first two birds I had a hard time getting through the neck in one nice slice. I purchased a bleeding knife for the next batch. Has anyone used one of these? I believe it is more of one you stick in then slice out. I am just nicking the artery and it is taking too long for my birds to die. Any helpful hints? I have another batch to do and I want them to suffer as little as possible. I really want to do the bleeding out technique.
