A friend is going on a guided wild turkey trip and has asked if I am interested in any feathers for my fly tying. I have only used some of the Mottled turkey feathers for muddlers and some Atlantic Salmon patterns at $6-8 bucks a matched pair, I use them sparingly

Other than the tail feathers, what else should I ask for? The guys that go on the trip every year just toss them and keep only the meat......

When I get them, is there anything special I should do to them? wash, freeze, etc. I don't want to comtamintate my current fly tying supplies with bugs.
