We plan to acquire our first chickens this fall. I have been working on a design for a chicken coop, and feel pretty good about everything except for ventilation. The coop will be roughly 10' x 6'. The nesting boxes will be along one of the 10' walls, and the roosts will be on the opposite side. I'm not yet sure how high the nesting boxes will be from the floor, but I know that the roosts need to be higher to prevent the chickens from roosting in the nesting boxes. I plan to install vents near the top of each 6' wall. I would like to put several windows along one of the 10' walls, with either more windows or vents on the opposite wall for cross ventilation. I'm thinking that maybe I should go with vents on the opposite wall, near the top of the wall, so the hot air can escape and draw cool air in through the windows. I understand that it is important to not position the roosts so they will be in the direct draft from vents/windows. Based on this, is it better to place the windows on the wall opposite the roost below the roost levels? Or since I plan to have vents up high, will the air current be moving low to high, meaning putting the windows at the same height as the roosts are ok? I'm guessing that having the windows on the same side as the roosts is a bad idea because of the amount of air that would blow on the chickens at night, is this correct? One last question. Is it better than the windows face south/southeast, so the chickens get early morning light (assuming I've not already let them out for the morning)? I'm thinking of using wooden shutters on the outside to cover the windows during the winter, to help reduce heat loss.
