I'm a city girl, now a grandma. DH and I tried our hand at butchering a few roosters the first year we got started in chickens here only to find, even with coaching from his mom, that we were horrible at it. I won't go into detail on parts of it, but even once the birds were dead we had problems. You have to careful not to contaminate the meat during evisceration. There are right ways and wrong ways to remove the feathers. Dispatching and cleaning four birds took us the better part of a day and left us both completely spent, determined never to do it again.
It wasn't so difficult emotionally, we just learned we were really bad at it and too old to want to learn. Fortunately, we found a lovely Mennonite lady near us who does a wonderful job of it and only charges us $2 a head. I usually take her no more than four at a time, as I can't fit more than that in my refrigerator to age for a week before putting them in the freezer.
I feel no shame in doing it this way. I know Mrs. W is fast and efficient, which we certainly are not. I want my birds to have a humane end, and it's certainly worth $2 to provide that for them.
Good luck to you. I hope you find a solution that works for you.
