One of my chickens dropped dead today!

I'd had my eyes on its feathers for a while but had assumed I would get to pick when it died!
Any way I've kept the feathers from the neck area and the saddle hoping they could be useful.
Here are some pics
neck
and saddle
the neck ones look more useful theres a range of sizes and shades of browny orange. not sure if the black tips are useful as I thought they would be when they were still on the bird.
saddle ones I'm not so sure about though - awful lot of fluff not much "feather" - "chickabou" maybe?
So I'm just looking for opinions on if they are worth keeping and using and maybe suggestions for flies that could use this colour hackle. or just bin them?
