All the birds I've plucked, I have kept the feathers for fly tying. For all but the last two mallards, I've simply plucked the birds and stuff the feathers in a ziplock. I made it a point to separate the CDC feathers this time and place them in a separate bag. I should have done this with all the birds but I simply did not know where the CDC feather were located. The CDC feathers, if you don't know, is on the back side of the duck just above the tail feathers. There is quite a few too that will make some nice dry flies.
