Chickens were first domesticated in Asia about 8000 years ago. The average American eats about 80 pounds of chicken per year, which makes it by far the main source of animal protein in the American diet.
The polutry industry has created bottom-line driven factory farms where chickens live and die in terrible conditions. They're full of antibiotics and chemicals, and genetically engineered to grow artificially quick. The people who work in such factories also suffer terrible injuries in the attempt to keep up with speeded-up assembly lines.
