Pilots beware! You’ll now need to keep a sharp eye out for stray sheep, donkeys and llamas when touching down at the Chicago O’Hare Airport. These herds of friendly animals are all part of the new natural lawn care system employed to maintain the 120 acres of airport land. The airport even hired shepherds to keep track of the new additions to the team. One proud goat couple is already pleased to announce the successful birth of their first airport baby.
