Lost to history: The “churk”
More than a half-century ago, researchers at the Beltsville Agricultural Research Center outside Washington, D.C., engaged in some creative barnyard breeding.

Along the way, and ostensibly quite by accident, an interim stage of this work resulted in a rooster-fathered hybrid that the scientists termed a churk.
