How cold is too cold for my chickens?

You’re very welcome! Hope I didn’t overload you!

Thanks, @BantyChooks - gotta earn that crown you put on my head, don’t I?

At 5am this morning it was 5 Fahrenheit. Inside the coop was 12 degrees. My 14 week old Barred Rocks were fine. They jumped down and straight to the feeder and heated waterer in the coop. And then they were out in the pen after their fill of feed and water. I open the chicken door at 5am year round, , and close after sunset. The chickens go in and out as they please.
The day before it was 14 in the coop.
My 31 month old Golden Comets went through two winters with several nights of -13 and -15, -7 and -9 in the coop.
I've read many times that chickens are OK down to -20 Fahrenheit. But haven't gotten that low here, missed it by 5 degrees last winter and I'm fine with that. I hope it doesn't go below zero. Average low here is 17 above in January. We broke records yesterday for the coldest day in November.
No more records PLEASE. GC
