The Evolution of Chickens: From Ancient Origins to Modern Industrial Production
TLDR Chickens, descendants of a bird domesticated over 10,000 years ago, have undergone significant changes in the last 70 years. From their origins in Southeast Asia, chickens spread across the world, with selective breeding resulting in various chicken varieties. The Second World War led to the popularity of chicken as a meat in the United States, and the breeding of larger, faster-growing chickens has transformed the industry, although there is now a trend towards raising free-range chickens for better quality and living conditions.
