Chickens are the most common bird species on Earth, with an estimated 52 billion individuals spread across five continents. This documentary traces their journey from the forests of Southeast Asia to farms, cities and islands around the world.
In Thailand’s Khao Yai National Park, scientists study the Red Junglefowl, the wild ancestor of the domestic chicken. Research by Professor Eben Gering explores how domestication changed the birds’ behavior and even their crowing. The film also follows chickens as they adapt to new environments, from rooftop farms in New York to urban settings across the globe.
