In 1911, the University of Delaware adopted the Blue Hen as its official mascot.

In the 1930s, the initial physical mascot was a live blue chicken that was tended to by members of the cheerleading team.
It is unclear if it was a blue hen, or a chicken with blue feathers, as it is believed there are no true descendants of "fighting blue hens of Revolutionary War times."

Starting in 1950, several costumed "Fightin' Blue Hen" mascots existed.
Little is known about them besides the fact that they were "a variety of light and dark blue suits."
Few photographs of them can be found.
All of the costumes were presumably retired before YoUDee appeared.


One reader of The News Journal in Wilmington requested that the one of the old mascot's costume be displayed in the nearby Bob Carpenter Center).
This reader was not alone, as a petition with over 1,000 signatures circulated the state of Delaware, demanding the same.
The Athletics Department responded and objected to the petition on the grounds that there's was no room for it, and that "it would be inappropriate."
Articles from the time indicated that at football games, the old mascots were ridiculed and pelted with items such as "marshmallows" and "batteries" by students on a frequent basis.
It is unclear if this was a recurring skit coordinated by the mascot team, or represented student emotions at the time.

A successor mascot would take its place.
When the University of Delaware President David Roselle was questioned as to why there would be a new mascot, he said "[well], the obvious answer is, the old one wore out."
