Believe it or not, Kauai has a population of wild chickens that roam about the island of their own free will. Brought to the island by the Polynesians as a food source, at some point in history these hens and roosters escaped from farmlands and cockfighting breeders to frolic in the wild (or the city streets). Supposedly when Hurricane Iniki hit in 1992 chicken coops fell apart and the domesticated hens took flight. With no natural predators the fowl multiplied freely. After a few nights on the island you get used to the cacophony of cock-a-doodle-dos that begin around four in the morning.
