I've killed quite a few birds before and i did one yesterday (for eating) and the cleaver i was using had usually been fine, but i was doing bantams before and this was a full sized rooster, the blade wasn't strong enough to get through so unfortunately he had a bit of painful death but it was over in a few seconds, so now i need a new way to kill them as i'm doing one next weekend, so i've looked around and found the best option would be via snapping the neck, so what is the best way to do so, i've heard just picking it by the head and spinning it but i want to make sure first
