Tried it, but it was awkward and didn't work for me. I only tried it three times, and only succeeded in killing the bird twice; an axe keeps me a little further from the blood, and I'm more squeamish than I like to admit. With enough practice, I'm sure you could get it to work, but I was afraid I was going to hurt the chicken in some horrible way and leave it to suffer until I could figure out how to dispatch it properly.
It should be noted that it is almost always easier to pluck a young bird than an old bird, which may have been part of this guy's success.
