For the CX, I use a pair of sharp shears to cut the skin around the neck, then use poultry shears to cut along the spine. I cut the spine right above the tail and then cut the skin around the anus. It's so much easier to remove everything this way, including the lungs. After resting I cut the spine out, remove the wings, separate the breast for the thighs/legs, and cut the breast in half. I leave it all on the bone and bag separately by type. Sometimes I only cut in half and bag a half chicken, if it's on the smaller side. For my extra cockerels from the layer flock, I also cut along the spine and follow the same procedure but I don't cut up for freezing. They don't have enough meat to justify separating them up.
