According to The Humane League, 94% of all animals raised for food are on factory farms. This means that 130 billion farmed land animals suffer every day. Chickens are one of the animal groups most affected, and often suffer in unimaginable ways, including by being kept in very small battery cages.

Through its campaigns, the Humane League (THL) works relentlessly to end the abuse of chickens raised for food. Specifically:

- THL puts pressure on companies and corporations to improve welfare standards for chickens.

- THL promotes corporate campaigns internationally through its work with the Open Wing Alliance, which it founded in 2016.

- THL takes a highly collaborative approach to its advocacy. It trains individuals and organisations, shares resources, and works to make the animal advocacy movement more effective.
