No mites and their not pulling them out. This is going to sound stupid, but all the feathers around their bum are the one's they are losing. They are really fuzzy and their are no bear spots or mites/lice. If they lie down in the grass the fuzzies are in the grass. Maybe two to three in each spot. And it just two of the six that are loosing the fuzzy feathers. It seems not so fuzzy feathers are taking the old feathers spots.
