Key West has a love/hate relationship with the local chicken population. Yes, you will see and hear them everywhere. Some locals love 'em. Some locals hate 'em. You won't be able to avoid them. They're as much a part of the island as all the cats you will see everywhere. Stop in at the Chicken Store on Duval for a bit of the "pro-chicken" side.
it's all fun, and part of the flavor of the place.
