A MARTÍNEZ, HOST:

Good morning. I'm A Martínez. Why did the chicken cross the road or the train tracks? A chicken recently got loose on a Mexico City subway line. The bird temporarily stopped service and sent several workers on a wild goose chase. The video shows maintenance workers and officers in hard hats, using everything from brooms to a jacket to try and catch it. They eventually succeeded, and service was restored. Wow. That was one pollo loco. It's still MORNING EDITION. Transcript provided by NPR, Copyright NPR.
