There's a New Hampshire thread in case you're interested. It's not too lively but perhaps you could change that.

I had no idea. Thanks

You have a really nice set-up! It looks like it locks up pretty tightly when that upper window is fully closed - probably too tightly for good night-time ventilation. I assume the window has hardware cloth under the flip-up cover? If it doesn't, putting 1/2" welded mesh on the opening would be a good idea.
There are articles on summer/winter ventilation right here on BYC. A good one to start with is this one:

Again - You're giving me a bad case of coop-and-run envy!

Yes, we did install hardware cloth. Based on your suggestion, I opened the door about an inch for the night and it is above the roosting bars. I am concerned about the coming cold weather (sometimes below 0 for hours). We have a heat lamp (covered of course) but won’t use it unless it gets really cold. Thanks for the advice.

That should work for now - and even in the super cold temps. If they stay locked up tight with no way for moisture to dissipate, you'll end up with frostbitten combs & wattles. At that point they become even more susceptible to cold. It's much easier to increase the ventilation now, before you have to do it in the bitter cold ... and yes, I learned that particular lesson the hard way!
