Hello, i use garden scissors similar to the one at the picture below to slaughter my chickens, so far i used it 4 times for some roosters. I tie them upside downby the legs and use a net to tie them around their wings, then i tie the head on a large piece of wood to keep their head in place and i also cover their head and let them relax, then i slowly put this tool on the neck near the head with the cutting edge in "front" of the neck i mean not the bone side and i use it while they are relaxed. They dont seem to suffer. My question is that "humane", is there something wrong with it what are the "ups" and "downs".?
I used to keep chickens just for the eggs for the last 3 years but this winter i bought 2 patches of 5 and the second patch of 5 layer hens had 4 gigantic hungry roosters, i want to say i am a begginer to slaughtering. I ended up using this tool because i can stay back, i dont have to touch them and i can walk away fast enough to avoid the blood and also avoid their dying experience. I return after 30 seconds when they are done and remove the head because that tool does not cut the skin at the back of the bone. It does cut everything else at the front and the bone. Then i cut a piece of the neck with the knife and throw it away as i clean them, where that tool made the first cut.
