New SoundMinds Radio: Factory Farming and Urban Planning: Killing Two Million Birds With One Zone. Australians consume over 600 million chickens each year. The vast majority are grown in intensive, vertically integrated factory farming operations called ‘broiler’ farms – some of which house over a million chickens at any one time. While many of us can barely imagine what a million chickens in a shed might look or smell like, peri-urban and rural communities often have firsthand experience. Australians consume a lot of cheap chicken, but planning conflicts show not everyone appreciates an intensive chicken factory as a neighbour. Factory farms are a frequently polarising form of agriculture.
