I now process my own chickens at my kitchen sink. Before I gained the confidence to do it myself, my neighbor processed all of my poultry with x-number of birds to her, in exchange for her processing for me. I let her pick which she wanted, assuming she'd take the biggest birds (which was fine by me), but even that was like two birds out of ten for her trouble. She taught me how to process my own, without ever making me feel pushed into it.
In a nutshell, I bind their feet with rope, hang them (by their feet) from my mango tree in the back yard. Chop off their head with a branch trimmer, cuts 1 to 1 1/2 inch branches and chicken necks, with ease; I use the sort with the long handle. Release the bird and walk away for a few minutes while the bird bleeds out (and flaps its wings etc). I don't want to see that part, but know that it's needed for the process. After a few minutes of bleed time, I gather the bird, and take it to my kitchen for processing. I don't pluck. I sacrifice the skin to save the time and trouble of plucking by removing the feathers, skin and all. I also don't go for the 'full' bird when done approach, opting to remove the thigh quarters first, then removing the entire breast. Hardest part is separating the wing from the carcass. With the majority of the meat safe from accidental puncture of the entrails, I then harvest the heart, liver & gizzard. Pull out the remaining entrails and discard (or feed to your dogs, pigs, etc.) Cut the back in half; discard the bony half (or feed to your other animals, as mentioned before), and put the meatier half into the soup pot.
There are many YouTube videos on the subject of harvesting your own poultry.
