There is always a time when keeping poultry that a quick and humane method of dispatch is required.
Poultry being flock animals do not show ill health until they are overwhelmed. Others in the group will shun them at this stage leaving them vunerable to attack from predators in the wild.
Hence here is the cone.
Hang the cone on a post or wall.
Place poultry head first to dispatch quickly from below.
Safe and humane.
