Should I keep them in coop when it's below 32

[Akane]

Mine currently are not interested in leaving their giant coop and haven't been since I put them out there last fall. However I do leave the door open if the temps are above 0 with no bad weather or strong wind blowing in. Sometimes Kimi goes out and scratches around and the others stare out the door. They don't act cold. They just don't care to go outside yet. I haven't seen any behavior that they are too cold even when it gets into the negatives here. My roo did get frostbite but that was on a night that was barely below freezing after being fine in -10F so I'm pretty sure he got his head wet drinking in the evening and that caused his comb to freeze that night. Moisture greatly increases the chances of frostbite. They do better when it's really cold than when it's cool and rainy. They actually seem happier now that it's winter and everything stays frozen than in the late fall when we'd have cold to freezing rains and everything was damp.

my chickens are 10 weeks old and I have had them out in the coop since they were 5 weeks old. I live in Indiana and it's starting to get down in the teens and single digit cold here. When I first opened the door to the run, it was around 40 degrees. The first two nights I had to go out at dark and physically pick up most of them and put them in the coop. I did this for two nights. Now they will go out and come back in on their own. I open the run door in the morning when I go to work and go out to shut it at dark. They are all back in the coop. I've noticed they don't wander very far from the door or stay out very long when it's cold out.

Mine stay in, but I leave the door open for them. But they are also laying age.

But. Since our coop is NOT insulated and turns into a fridge. And we are in for a REALLY cold snap here over the next few days/nights.
They are going to be coming into the house at night.
