I have had numerous birds over the years go into a full fledge, full body naked molt in the coldest November and December. While we are not horrible single digits, we often are low 30's and 40's with constant drizzling rain. I have never had a molting bird get sick. I can't imagine how they stay warm, but they do. I would be concerned that your bird will have to be reintegrated back into the flock which can be difficult during molt, when they look odd already. I'd personally hesitate removing her.
I have used Nutrena Feather Fixer, and honestly, it does seem to help them get through a hard molt much faster. You might try that for a month to help her through this.
Also supply lots of cracked corn, that helps produce body heat. And, Black Oil Sunflower Seeds which are very high in protein and fat for good energy.
