I wouldn't worry. We have 50-degree temperature variations all the time, and they've always been fine.Id bring her in tonight if I have to but will she adjust to the climate when brought back outside?
In the winter, they have less than in the summer going from a 40°F heated coop to the outside, where temperatures typically range from 0°F to 20°F.
If there's a drastic difference, like 70 to 0, you can wrap her in your coat and open it slowly over a few minutes.
