Chickens as traffic control

1975: Rather than installing expensive signs or speed bumps, Napa, California experimented with using chickens to slow down motorists on one of its streets — Streblow Drive, bordering Kennedy Park. They simply let 85 chickens roam the park and street at will. Said park superintendent Bob Pelusi, "Only occasionally does an errant driver charge through the flock. In the nine months we've had the chickens on the job, we've lost 12 of them — gone in the line of duty, so to speak."
