In the United States, more than 9,000,000,000 chickens are killed each year. Globally, more than 45,900,000,000 chickens are killed for human consumption each year.1
At any given moment, there are 284,000,000 chickens exploited for their eggs in the United States.2 Each year, 100,000,000 of those hens are slaughtered after they decrease in productivity. 98% of hens live in cages—the average space per animal is 50 square inches (smaller than a standard notebook paper).
