Sheep, Goats, A Donkey Arrive at O'Hare Airport To Help Maintain Airfield
CHICAGO (CBS)-- It's a sign of summer at O'Hare International Airport.
A herd of 30 grazing animals arrived Friday to help clear overgrown vegetation around the airfield. The herd included sheep, goats and a donkey.
This is the sixth year for the program, which city officials say is an eco-friendly way of keeping the airfield safe and maintained.
