In all of my research, I have decided cones are the best way for me personally. I like that they quickly lose consciousness and you can get most of the blood drained because the heart beats longer than if you just remove the head. I also like that they die calmly and the cone holds their wings close to their body to lessen the risk of bruising the meat. My personal plan is to withhold food for 18-24 hours also, to keep everything cleaner during processing. I have killing cones, a camp stove with a stock pot for scalding, a plucker (yardbird), and coolers for keeping the birds cold. I have a fillet table for evisceration and butchering, which is convenient because there's a hole I can put a trash bucket under for everything. I also have shrink wrap bags to store them in and plenty of freezer space. I am thinking I'll likely process the 5 Cornish crosses I have in about 3-4 weeks (when they're about 8 lbs live weight), and I'll update with my experience when I've actually carried it out.
