I'm afraid I had to separate the molting chicken. She's doing well and her feathers will grow back soon but chickens are a little like teenage girls. Anyone who's different gets picked on.
Chickens feel very strongly about looking beautiful and have many spa days (or dust baths, if you will) to achieve the right shine on their feathers. Without her feathers she was clearly different and wasn't being allowed to sit at the lunch table with the other girls. She was getting pretty hungry but they didn't want to hear it and told her to talk to the tail feathers.
