1.Gas killing. PETA believes that gas killing is preferable because it ensures that chickens are insensate before the painful procedures, whereas electrical stunning is less reliable. According to the Human Slaughter Association, the type of gas used must be suitable for a commercial environment. The efficient gas mixture must meet the following requirements: Be non-aversive (causes no detectable signs of distress) Induce loss of consciousness in birds as rapidly as possible be reasonable cheap and safe to use in industrial conditions be relatively easy to contain within an open container have no side effects on meat quality Carbon dioxide is heavier than air (therefore easy to control), relatively cheap and an anesthetic gas which produces rapid unconsciousness when inhaled at high concentrations. However, it is acidic, induces a sense of breathlessness, and is thought to be highly aversive to chickens at concentrations above 30%. Argon is an inert gas (colorless, odorless and tasteless) that is heavier than air, kills chickens by anoxia and is non-aversive. Argon is more expensive than both carbon dioxide and nitrogen. Nitrogen has the same welfare advantages and properties as argon except it is slightly lighter than atmospheric air, so may be more difficult to contain in high concentrations. Some disadvantages of gas killing need to be taken into account which include more moving parts in the system compared to electrical waterbath stunners, therefore there is an
