Check out commercial feather dealers. I bought some pheasant tail a few years back from a commercial feather dealer. I got 18 really nice pheasant tail feathers. They were all nice and long and the individual fibers are about 2 inches long. I paid around $20 for them but worth the price. Unfortunately, I can't remember the name of the company. I thought I saved the paperwork but can't find it. Anyways, put "feathers for sale" in your browser and several sites will come up.
