How has this humble forest animal managed to conquer all continents, all territories, and become the most abundant and diversified feathered species on our planet? Today there are over 19 billion on earth, three times more than human beings, and many more than any other species of wild birds. How did this darkly plumed forest species become so diverse in color, form, and behavior? What is the everyday life of the hens and roosters that surround us? Battery-farmed in Brazilian hangars, raised outdoors in the English countryside, in Filipino combat training centers, in survivalists’ bunkers, or on New York’s roofs, chickens can live many different lives. This documentary will explore the world of mankind and chickens in order to unveil the mysteries of the unprecedented success of this unassuming bird.
