These are the grizzly style hen feathers.
These feathers range from small size 14s (maybe 16s at times) with lots of size 12s, 10s and up to larger sizes. Excellent for soft hackle flies.
These high quality hen feathers are full of fibers so it takes less wraps to get a full hackle. You can sometimes get more than one fly out of each feather because they are long and slender with more consistent fibers.
