You do indeed have some great fletching.
The orange flight feathers are neat, as well as the barred ones. The barbs from the tail feathers, are highly prized for fly tying. As are the blue green, other colored breast, and back feathers. Good find, and save! Check around the feed store for other feathers from the other peacocks, and peahens.
You definitely have some trade material, for any of the members who fly fish, or make flies, or want exotic feathers for various projects.
the back and breast feathers would make nice decorations for bows, arrows around the fletching, on possibles bags, quivers, on and on. Limited only to your imagination.
Of course you could always drag it into the kitchen, and tell who ever is in there, hey, look at the chicken I found down by the nuclear plant.......
