CHICAGO -- Chicago's O'Hare airport looks something like a zoo after hiring 25 new airport employees.
Goats, sheep, llamas, and burros were hired to keep the 120-acres of grass and other vegetation around the airport in top shape.
They cost less than hiring a lawn crew.
The animals are separated from the runway by a fence.
