I'm so happy to hear Sunshine sounding a bit better!
I don't know anything about chickens, but do you have a garage you can fix up for Sunshine to stay in at night or in the cold til her feathers grow back? I read here at BYC that hens don't like to be out of sight of each other, so maybe keeping Faith and Sunshine together in the garage with a heater for when it gets cold? They sell heaters that are flat panels that radiate heat but don't burn you if you touch them. Maybe a "How Do I Winter a Naked Chicken" would find good answers in the flock management thread...
I'd suggest a sweater, but I'm guessing other chickens might peck at it and at Sunshine.
And ... what if she doesn't like your fashion sense?
