The most important thing is that there are no strong drafts blowing in. You'll find that a chicken fairs far better in bitter weather than in the heat. Anything over 90 degrees calls for some extra measures to keep them alive.I have a lot of ventilation built into the plan, was even considering doing a ridge vent on the roof.... gosh I would really really be worried about not insulating anything with how cold we get. I know some in our area lost birds this winter due to the "polar vortex" that hit us a few times.
When you start shopping for chickens, be sure and look at the breeds that are cold hardy. All of them are to some extent, especially the heritage breeds. I have RIR's, Orps, Marans and BR's and they all did great this past winter.
