In material catalogs we see Grizzly hackles given a lot of promotion possibly because of their distinct photogenic coloration. Could that be the answer to my quiery? They also seem to be paired with brown in so called "starter sets". It seems that unless you specialize in Adams, Humpys and various Stimulators the emphasis would be on Duns and Light Gingers with the Grizzly and Brown getting a second rating in usefulness. Or could the reason be that the genetic strains of Plymouth Rocks and Rhode Island Reds are more easily developed and maintained by the breeders?

I also wonder what all the "hoopla" is about concerning Cree hackles. You don't really need them. Wen is one called for? If you bought a good one it would be too valuable to ever use. It would be relegated to a class of materials I'd call "Petting Stuff" for showing off next to a perfect Jungle Cock neck. It must be a supply and demand story.
