Gone crazy,
I wondered about that for a long time too.....(the ventilation question) the answer seems to be to have plenty of vents high up, like under the roof line. Warm air, including moisture and ammonia fumes from the poo, rises, and if you can get any kind of cross draft (opposing vents) then it would carry that air out of the coop. High vents would hopefully not blow on the chickens, who should have a nice layer of warm air in between their bodies and feathers. Moist air would also condense and freeze their combs faster. Hope I have that right!
