Have you considered that you may have an aggressive hen with a lot of testosterone? I’ve read that it’s not that uncommon . The bare spots are consistent with being mounted by a rooster, but since you don’t have one, you may have a rooster wannabe.

One of the ones that is Losing the feathers is outside right now picking up her backside. That Hass to be a pest problem correct?

Actually they all seem to be picking at themselves a lot. This is right after coming off roost. Normal preening, or attempted pest removal / irritation?
