The Coq de Leon is the oldest known chicken strain specifically bred for fly tying feathers. References to these rooster feathers, and the special flies tied with them, are found in manuscripts going back to as early as 1624. 

Excellent natural tailing fibers from the center top feathers, sometimes called the "spade hackles". Also provides large size wet and dry fly saddle hackle for Skater, Hexagena, Wulff and other larger flies.
