Factory Farming

Out of the 30,000,000 chickens in the UK, 85% are housed in factory farms.

Turkeys can no longer breed naturally because their breasts are too big. (source)

Chickens naturally scratch around in the soil to find food. However, in factory farms they cannot do this. To beat boredom they have turned to Cannibalism. To solve this problem, farmers cut their beaks off causing excruciating pain for the animals. (source)

Most factory farmed chickens are kept in sheds containing 20,000 birds in cages that contain 4 or 5 birds, and are stacked up to 6 cages high. Over 2,000,000 of these chickens die in their cages each year due to disease.

In the US, some cows in factory farms are fed chicken faeces because it is cheaper to do so than buy proper food. (Source)
