Pickespickles, you're neither a goof nor a dork for showing those final kindnesses to your birds. You go ahead and do whatever makes you feel best, and helps you do the best job of processing your birds. Some folks think that "humane processing" is an oxymoron, but I don't. Until there is a breed developed that will butcher itself, the next best thing is to learn to do the job humanely, which is efficiently, quickly, and with the least amount of stress & pain possible.
SandraMort, I pray for grace & strength for you & Carress. You can take pride in acquiring this basic survival skill that was once so commonplace, now becoming lost to most in our modern society. Keep in mind that these birds' purpose is to be meat. It's their job, and your job is to learn how to process them well. They'll certainly get better treatment from you at the end than they would in some commercial plant!
Don't let any post-mortem flapping upset you, it's just a basic nerve response & not an indication of pain. In a few days you'll have an incomparable meat dish to serve with pride & appreciation!
Let us know how things go for you.
