A sharp knife is all you really need. What I do is take the chicken and wrap it securely in an old towel (kind of like wrapping a baby up so it feels secure). At this point, its body is contained in the towel, and I can position the legs so they are together, while the head is sticking out from the towel. I sit in a lawn chair, and hold the chicken between my knees, mostly upside down. In this position, and with the help of the towel, I now have both hands free. With one hand, I hold the head and neck and can stretch it out so that it is in the correct position. With the other hand, I hold the knife and using the forefinger from the knife hand, feel for the jugular. Having the close contact with the chicken securely between my knees versus in a cone, I can feel it relax. My goal is for the chicken to be as relaxed as possible, partly for humane reasons and partly because my understanding is that all animals will bleed out better and the meat will be most tender if they don't have stress hormones streaming through their bodies in the minutes before death. I stroke the jugular area and talk to them until I feel them relax, and then slice quickly across the jugular. I wear muck boots so any spray can be easily washed off. When the wings start to flap, they are contained by the towel and my knees. It is quick, easy, and while I will never enjoy the task, I at least don't feel that they are suffering.
