I feel it's more human to both break their necks and slit the throat, so I do it that way. I killed a cockerel last night by breaking his neck by hitting the back of the knife I had holding against the back of his neck, then slit the throat. Sometimes I cut the head off in one cut if I can, depending on what tools I'm using. I find a hatchet works well for meaties, but it just bounces off those tough hackles on cockerels and roosters, even if it's sharp enough to shave with! I soaked him in salted water overnight, that takes care of any excess blood. I wish I was strong enough to break the neck with my hands, then slit the throat, I think that would be less traumatic, but I haven't been able to do it. I don't know if I'm not strong enough or if I'm simply not doing it right. by the way, it was a 5 month old hatchery Blue Andalusian. I was very disappointed by all the red in his feathering and complete lack of black lacing, so I wasn't going to breed him so he had to go. Scrawniest bird I have EVER butchered! LOL! He was every bit as tall as my old Delaware rooster, but weighed only 2.5 lbs after cleaning the carcass! SCRAWNY! I hope he at least tastes good! lol. I think that Dellie roo was 8lbs after cleaning. I need to get some more of those. He was the best tasting chicken ever, too.
