Hello and welcome to BYC! 
At this age they should be ok down to the upper teens Fahrenheit, unless it's getting into sub zero temps they should do fine. I'd definitely let them sleep in the nest boxes with lots of bedding or some other enclosed box type thing. A large wire dog crate with a blanket draped over 3 sides and the top will work too. Keep an eye on them but I think they will do ok. By late winter you can get them started roosting on the bar. Best wishes with your babies!
