Is it to cold for a broody to hatch eggs?

[MRNpoultry]

I let my chickens free range but they come back at night and lay there eggs, so I shouldn't have to worry about not finding her nest some of mine use to sleep in the woods. They set on about 12 eggs and I 4 today, hopefully in the next couple of days she will start to go broody. I'll give an update if she starts to sit.

Thanks
