Keith and Maryann Frist say an egg laid by Lucy, a Rhode Island Red at their Lancaster County farm, weighs in at 140 grams. That's about twice the size of a typical jumbo egg from a grocery store.
The Intelligencer Journal/Lancaster New Era reports Maryann Frist submitted an application to Guinness World Records hoping to have the egg certified as the nation's biggest.
Lucy could certainly have some competition, though. A West Virginia teen had a chicken egg weighed in at 5.5 ounces last week by the state's Department of Agriculture. That would make it more than 155 grams.
