You'd be surprised how many feral chickens are perfectly fine with sleeping outside. In fact, Florida has a large population of them. The one who consistently sleeps outside is likely the hardiest chicken you have. I know mine are. Don't worry about her. She has the opportunity to get in out of the weather should she choose to.
I've only had one chicken to freeze to death and that was one who slept in the nesting box away from the other chickens last year. I have yet to lose any of the ones that sleep outside.
