Best thing i have found, get a thermometer! and watch for condensation build up. My big hen coop is well vented, and has a big window which is right by their roost. I have found watching the actual birds tells you a lot about what is working and what isn't.
My birds wintered just fine last year, and the absolutely yo-yo of a fall were having is not proving to cause any concerns either. Perhaps, one day i may try an open air but i do know for it to work it has to be on the right scale, i have no need for such largeness all the chicken breeds combined amount to only 15 lol
