Well, I am really clumsy. So would you be if you had arthritis, carpal tunnel, and sometimes the joys of trigger finger, another painful and clumsy hand issue.
Yet I manage to make some very intricate craft items, garden, cook, (pretty much everything from scratch, and I usually bake my own bread) and raise chickens. I sometimes solder electronic and jewelry items, I build things, I do all kinds of stuff. I sometimes have to work slowly and carefully, but I have the patience to do these things anyway.
I just have to find a way to kill the chickens quickly and humanely without cutting myself up. I don't think it's very humane to fumble through the way I've been doing. I'm not giving chickens "human emotions", but I know they feel fear, and I know they feel physical pain. I'd like to make that part of death as quick as I can. I'd like to find a better way, that works better for me. Whether anybody else likes the idea or not.
Others may think I'm an idiot, or think a person can't manage to point a gun down without shooting off a foot, (a softwood stump, such as cedar, would work fine. I wouldn't suggest trying it with a hardwood such as hickory or seasoned oak) or handle dry ice safely, (yes, I have handled it. When I worked in medical labs for many years, I did so daily. It just takes a small amount of common sense and reasonable safety precautions. It take more than a casual touch to lose a finger. I also worked with liquid nitrogen, to freeze and transport biopsy specimens. A little riskier, but still, not a huge hazard if you don't do something stupid like stick an appendage in it.) A container attached to the inside of the box to put a chunk of dry ice in would solve the problem of a chicken stepping on a slab of it. These details are not the big, insurmountable problems they're being made out to be. Please rest assured that I wouldn't be using a machine gun, assault rifle, or anything like that. A pellet gun or a .22 would suffice. Yes, I know, they can still hurt people if you're careless or an idiot. I will not be holding a chicken down with my foot to shoot it.
I don't think I need to discuss this anymore. Next time I butcher some roos, I'll try whatever I come up with, and maybe I'll post what worked best for me. I don't care if others choose another way. I just want to share what I learn with others who may be having similar difficulties.
Oh, and not everybody has somebody handy to just do this sort of thing for them. When my DH is home, he'll do this if I want him to, or help me, but he's not always able to be here when when things need to be done. I want to be able to do butchering well, on my own, when I need to.
