If you remove the flesh lay the feathers down in numerical sequence on a large piece of cardboard and number each feather. on the cardboard. doing that you will know exactly what orders the feathers should be reassembled in. Perhaps you could buy a piece of Styrofoam insulation or something similar and cut out a piece that has a radius on top and flat on the bottom. Then you could count how many evenly spaced holes you need for the fan. Then you could punch holes evenly spaced holes in the top radius and around the sides forming a fan, and insert and the feathers with a little glue on the quill, just remember the feathers should overlap a little. Then cover the foam with leather of cloth. Good luck perhaps some others here might have a better idea..
