yeah.
maybe you could actually try. you could look up how to make a noose, then just find somewhere high, and wait an hour for him to die.
Goodness, folks! No animal cruelty please.
Grab him from the roost at night, tuck him under your arm head in front, then hit him right behind the comb where the head merges into the neck and he will go limp.
Then chop the head right off with a meat chopper or a hatchet.
If you want to eat him, hang him by his tied feet to let him bleed out without having him flop allover the place.
