Hen Saddles
The search for more genetic chicken feathers has lead to the development of some rather stunning hen saddle capes which are useful for a wide variety of flies, one of which is the Hen Matuka (which see). These capes are available from Dave Roberts at featheremporium.com/index.html. Have a look. Dave also offers a great many other feathers.
Now here's a stunning hen saddle. I used this on to dress the Hen Matuka that appears on this blog.
A great Coq de Leon hen saddle showing the classic speckling that makes them so desirable.
Hen saddles come in a great variety of natural and dyed colors.
