I don’t have any experience slaughtering chickens, but based on my engineering judgment, I’d suggest the Craftsman Handi-cut. This is not a pair of scissors: it’s one blade that comes down against a flat, hard plastic anvil. This method will require two people - one to hold the chicken’s body with head outstretched, and the second to position the tool across the bird’s neck and provide a rapid squeeze of the handle. I will guess (and will leave up to your experienced judgment as to whether it’s the case) that chicken neck bones are thin/fragile enough that you’d be able to cut through them in a single motion with this tool lasting just a fraction of a second.
Badly mangled wing (probably a fox/racoon/orangutan given the feathery mess in the yard) that looks like it’s starting to fester. And she’s a family pet so…it needs to look like she just didn’t pull through. She’s still very tame and trusting and lets us pet her, but you can’t really pick her up without her making a fuss. This sucks–she’s gonna have to trust me one last time so I can do that cervical dislocation thing. Sweet, treacherous betrayal. Daddy’s drinking tonight.
We had a cat that got some sort of infected spot on its hindquarters. Dad, being dad, didn’t want to go to a vet, so I got to help with this adventure. He had acquired some sulfa-drugs for use on pets. Mother and I helped hold the cat down securely (using a towel to cover the head), and dad lanced the infected spot with his pocket knife (he did sterilize it), drained the pus (God it was nasty), and then coated the area with sulfa-drugs. Cat recovered nicely, but wasn’t happy with us for a while.
So this chicken is a family pet, have you thought about wing amputation?
You’re looking for plausible deniability on this death? Beheading probably wouldn’t be the best bet. Strangulation or suffocation appear to be the best bets.
Or you could tell them you took her off to a farm in the country, where she will be happy.
When I was a kid, back in the 50s, a farmer would come around with a truck full of chickens and eggs. If my mother wanted a chicken, she’d go out to the truck and show the farmer which one she wanted (they were different sizes). I never saw the actual killing, but according to my mother, he would just wring its neck. Then he somehow got rid of the feathers. So what we got was an entire chicken (including the head, feet and innards), minus the feathers. My job, which I loved, was cleaning out the insides, still warm.
I know some people would grab the head and swing it around like a lasso. Not sure if this is really different than simply wringing its neck. I also know that simply beheading it doesn’t necessarily lead to immediate death.
