I'm a beginning fly tier who has purchased Charlie Craven's beautiful book, Basic Fly Tying. I am attempting to work my way through it using the materials and instructions he has provided. (As you can probably can tell, I'm a little bit obsessive-compulsive.) I have arrived at the Adams fly. He has a very definite opinion that the wings on an Adam should be made from (grizzly) "generic barnyard hen necks". The only problem is where the heck can I buy some? Anyone got any they will sell me?
