Caponizing is an "artform" rapidly falling by the wayside. I know of some old timers around here that use to do it. I even have an antique caponizing set, but have never attempted it personally. Have seen a couple in real life, but they were for display purpose. Some people say that it is painful and cruel, but I don't feel it is. I have dubbed many old english cockerels, and I don't think its any more painful than that. Some will disagree, but its quick and easy from what I hear, and practicing on a dead bird makes much more sense. After all in vet school they practice surgery on dead creatures before you cut into a live one. Originally it was to develop better meat birds, and with the introduction of cornish x rock crosses, you don't really need a capon anymore, but its still nice to know about it and the history of the poultry industry.
