Molting now???

Just (with relief) found a great new home for 3 of 4 roosters...so, my hens are at peace and the barnyard is quite with Mr. Rooster, who is comfortably in charge.

However, one of the only two Ameracaunas is losing all her feathers! She walks along and they just fall off! In the morning, the coop looks like someone lost their life overnight. No one else is molting, and she seems generally fine (except one eye is kind of white and odd, now that I think about it).

I've increased her access to calcium (she's a crossbeak and it's harder for her to eat from the source the other hens have), and added vitamins to the water.

Any thoughts?
