Meet Tom Whiting. He has spent a lifetime breeding chickens that produce the best fly tying hackle in the world from his farm in Colorado. Even though that Parachute Adams or Golden Stone or Griffith’s Gnat you are using was probably tied in Sri Lanka or Bangladesh or by some guy in a cave in Bhutan, the hackle probably came from the good old USA.

Tom Whiting has devoted his life to chicken genetics and producing the perfect feathers for fly tying. The vast majority of their feathers are sent overseas, where most of the commercial fly tying is done.
