There are chickens. Everywhere. Sure, Hawaii has monk seals and sea turtles and humpback whales and geckos and albatross. But the animal most commonly sighted (on my island at least)... is the wild chicken. Some people say that farm chickens were set loose during Hurricane Iniki, and ever since they've multiplied to the billionth power. The roosters crow at ungodly hours; the hens roost beneath every other bush. They have no predators (hello, cats?) so they have no population control. We see them in parking lots, on the highway, on telephone lines, on distant hikes up in the rainforest. They are simply irritating, for no other reason than that there are too many of them! You can't even eat them - there's even a t-shirt that describes that the only way to cook a wild chicken is to put it in a pot of boiling water with a lava rock. When the lava rock is tender, the chicken is done.
