Why is the university of Delaware's mascot a blue hen?

YoUDee, the fighting Blue Hen of the University of Delaware, is definitely the most historical mascot In fact, he’s such a popular mascot that in 2006 he was inducted into the Mascot Hall of Fame and most recently, in 2009, he won the UCA Open Division Mascot National Championship. As the university’s story has it, YoUDee is blue and gold because his great-great-great grandfather, who fought in the American Revolutionary War, was given the Gold Medal for Valor at the Battle of Trenton. It’s said that those soldiers under the command of Jonathan Caldwell would often times carry about blue hens into combat in order to hold fights when the fighting died down or there was time to spare. These men are compared to the hens, and in essence seen as very brave and daunting.
