I got a book for my son called "pocketful of Poultry. In it there is "The Blue Hen of Delaware. It is the state bird of Delaware and a few hundred years old. They seem like an interesting bird indeed. It's recounted that the popularity of the "Blue Hen Chicken" goes back over 200 years. It's almost universally agreed that the origination of the "Blue Hen Chicken," as Delaware state bird, was during the Revolutionary War and that the battling ferocity and fearlessness of Delaware soldiers in battle was associated with the Kent County Blue Hen Chickens owned and bred by Captain Jonathan Caldwell. The courage and intensity demonstrated by the Delaware soldiers caused them to be referred to alternately as fighting "gamecocks" and as the "Blue Hen's Chickens."
