//The birds are collected from farms at night, transported to the site in the early hours of the morning, and kept in darkness until they are ready to be killed. Workers hang them upside down by their feet in shackles, suspended from a conveyor belt, or 'line', which then dangles them through an electrified bath. Their heads are submerged, and a high-frequency current in the water stuns them. The line keeps moving, taking the birds on to the slaughter area, where three men are standing ready to cut their throats.
The slaughtermen are Muslims. Dressed rather like welders, head to toe in protective clothing, they stand on one spot for eight hours with a knife, slashing the throats as they come by on the line while murmuring continual prayer. Being stunned, the birds pass by silent and still, making it an unexpectedly calm and mechanical job. Each man slaughters roughly a bird a second, and the slashing knife, dangling neck and spurting blood form a surreal rhythm, simultaneously horrific and rather peaceful. //
