Secret video reveals 'spent' hens' gas chamber deaths

Secretly recorded footage reveals hens apparently writhing in distress and desperately trying to escape as they are suffocated to death to provide meat for supermarkets including Tesco.

In what’s thought to be the first-ever video of its kind, the birds are seen twisting their necks as they are killed with carbon dioxide. They are also heard gasping for breath and emitting high-pitched shrieks.

The recording – which activists say was made at an abattoir endorsed by RSPCA Assured – shows hens being lowered into the gas chamber and dying over the course of several minutes.

Critics said the scenes laid bare the “horrors” behind egg production in the UK, including the fate of even free-range and organic hens.

Hens whose egg production has declined are dubbed “spent”, before they are killed and their carcasses are packaged for meat.

Animal-lovers have for years objected to the gassing of pigs with carbon dioxide, warning the animals “burn from the inside out” and suffer immensely in the last minutes of their lives.

Last year 99 per cent of “spent” hens were stunned and slaughtered with CO2; and 77 per cent of meat chickens were killed this way, according to government figures.

In recent years carbon dioxide as a slaughter method has gradually replaced electrical water bath stunning, which raised concerns over the inconsistency of stuns.

The footage, taken with hidden cameras, shows hens – female chickens used for laying eggs – twisting in distress as they die, and some birds apparently trying to escape.

The floor of the gas chamber was littered with dead birds that had jumped out of the crates, according to activist, filmmaker and vegan advocate Joey Carbstrong, who installed the cameras.
