High Quality Content by WIKIPEDIA articles! YoUDee (pronounced yoo-dee) is the mascot of the University of Delaware. He is a "fighting Blue Hen" and is named after the state bird of Delaware. According to the University of Delaware, YoUDee`s colors are Gold and Blue because his great-great-great-grandfather was awarded the Gold Medal for Valor during the Battle of Trenton in the American Revolutionary War. The men in the company commanded by Captain Jonathan Caldwell actually carried Blue Hens with them into combat in order to hold cockfights in their spare time. It is said that the men under Capt. Caldwell fought so bravely that they were compared to their fighting blue hens. On August 16, 2006 YoUDee was inducted into the Mascot Hall of Fame, in a ceremony at Philadelphia`s Love Park.
