More on ventilation.
The best place to put it is up high. Ideally, a foot above the chickens' heads when they are on the roost at night. They exhale warm moist air, which rises, taking it away from their combs and wattles. Moist air can cause frostbite, if the temps are low enough.
Ammonia from their poop also rises. They poop a lot at night. Look up "poop boards" as a way to keep your coop cleaner. There is about a 1/2" of what is called "sweet PDZ" on the board. It's also called "stall refresher," but you want the PDZ kind. I scoop up the poop with a kitty litter shovel, shake the PDZ back onto the board, and dump the poop in a bucket. 5 minutes, most of the poop in the coop is gone.
Here's a picture of my poop board.
