I use poultry shears it's more accurate than an axe and is also instant. The kill cone is a must for me but we made one easily. I still have to tie the legs together so they don't fly out running after removing the head. But the kill cone keeps them in a calm position, helps more blood drain, keeps them from flopping around making a bigger mess, and makes it so I don't have to hold it in it's last minutes of muscle spasms which is awful. There is a "humane" "guillotine" but I'm not sure about either. They consider it more humane because it breaks the neck rather than cutting, this is probably the least messy method. I'm not sure it's more humane. For quail, some just pull the head off. I'm not sure if that's possible with a chicken and to me sounds awful. As for the most humane method, I have tried looking into this. Such a difficult subject. Some beliefs is disabling the brain first is better because that way they are unconscious. They use electricity, a type of nail gun, or more aggressive smashing methods. In my personal experience, yet most people's fears, is that when you are drowning (which I nearly did) while scary at first as soon as a breath of water happens there is no pain just instant fading of consciousness, so I have wondered if that would be better but have no intention of trying it because I feel like that would be on another level and just can't. Even though I know what it feels like just feels like it would be wrong maybe. I have been trying to find out if there was ever an herb or something safe for using to sedate an animal prior to culling without lasting in the blood. I would love to see how it is dealt with in tribes currently in the Amazon! It's hard raising and harvesting food, but when you get it passed the point of being chicken and to the point of being meat it gets easier, especially the first time you get to feed your family the best food that you raised it is the most rewarding and comforting feeling but with a little sorrow and way more appreciation for our food than ever.
