As was said, no need to pluck any feathers. Simply lay the bird on it's back, head away from you, use two fingers and pinch the skin, obviously with some feathers, and gently pull the skin up a little and use a knife to cut a slit into the skin. Now, lay the knife down, stick your fingers in the slit and pull, using both hands, in opposite directions and that skin will open right up exposing the breast meat. Using your hands, pull the skin down far enough to expose all the breast meat. Now take your knife and cut following the breast bone, and fillet one side, then the other. Once the breast fillets are removed, pull the skin/feathers down around the upper thighs and you can fillet the upper thigh meat. I don't mess with the hole thigh becuase there are a lot of tendons, expecially in the lower part of the leg.

Fan and beard are straight forward. Find the base of them, and cut them off.
