Blue Hen

Bird

The Blue Hen of Delaware is a variety of chicken that was adopted on April 14, 1939, as the state bird of Delaware. The University of Delaware mascot, known as YoUDee, is also modeled after the bird. While it is not a currently recognized chicken breed, the fame of the Blue Hen can be traced back to the Revolutionary War. On December 9, 1775, the Continental Congress resolved that a military battalion was to be raised from Delaware, then known as the Lower Counties on the Delaware.
