Ok, this is good to know. I was thinking she was either stressed or too hot or both. Chickens don't typically like baths, so it stresses them out a lot. Then add too much warmth (or too cold) and they're really not liking it. It might be helpful to dry her off some, but be warned that will stress her out more. If you use a hair dryer, use the cool setting only.
For future soaks, try doing it in the evening (if you only soak her feet once a day) after she's roosted for the night and do it in a semi-dark room. She will be calmer then, so she won't get so stressed out. Only use enough water to soak the area so her feathers aren't getting wet and make sure she doesn't sit in it. That way you don't have to worry about drying her feathers off or she getting cold when she's returned to the coop.
