On Monday morning, workers arriving at around 5:30 AM to open Northeast High School in Philadelphia found dozens of hens and roosters wandering around the hallways. The birds were apparently brought to the school sometime over the weekend. The floors were covered with droppings and chicken feed. Most of the school's 3,600 students were sent home for the day because the school required extensive cleanup. A farmer was called to round up the birds. Police are checking surveillance tapes to see if they can determine the perpetrator of the fowl prank. The culprit will have to pay a hefty fine.
