Poultry stun knives are used to immobilize poultry before killing. Stunning is done through the use of electrical current delivered by the blade of the stun knife pressed against the birds neck. Stunning should be done before the throat is cut.
Many animal welfare organizations require stunning to meet their certifications.
Birds should be restrained unless using a stun knife. When stunning birds should be placed in hung by their feet in shackles to ensure proper electrical grounding. It is not recommended using killing cones as bird may not receive proper grounding as feathers act as an insulator.
