Thanks for all the feedback on the automatic door - its a big expense but I think I'll be happy to have the auto door once its installed so I'm excited to go ahead and order it. I might do that today.
Trish, on the ventilation, the coop is not as air tight as it probably looks from those photos - especially not at the moment, as the ridge vent isn't on so there is a 4-6" gap along the top of the roof line. I'm still trying to decide what to do as far as that goes. I found a 10 or 12' length of ridge vent in my barn (bonus: cuts down on the materials I have to buy - yay!!!) but as the coop is 14' long, that won't cover all of it. I'm considering putting on a cupola but don't know a ton about them. If I cut the ridge vent I have and put a cupola in the center of the roof, the ridge vent will cover the rest without having to buy any more. I even found a cute cupola at Lowes or Menards that has a rooster weather vane included! They're not cheap either though so I don't want to spend the money unless I'm sure it will make a difference. Does anyone have any experience with cupolas?
For additional ventilation, we are not closing in the soffits. I will cover them with hardware cloth so a raccoon can't climb the wall and get in that way, but otherwise they will be open on both sides. The window openings right now are just covered in hardware cloth. I have two storm windows that fit the opening and the plan is that the storm windows will eventually go on the outside, once the siding is up. But, since the storm window will cut down on the amount of air that gets in, I'm considering leaving them off in summer and just putting them on when I know a storm is coming in. Our summers tend to be so dry that I probably won't have to put them on very often.
Last, I plan to make a "screen" door for each of the doors. It will be a door covered in hardware cloth and will sit inside the solid door. Then I can use a hook to hold the solid door open, so that there is full air flow passing through from north to south. I just need to figure out a latching system that is easy for a human with her hands full to open, yet impossible for any other critter to open
. My helper suggested we could cut some more vent openings in the walls up high if we need to but I'm going to play that one by ear. One thing I do know is that despite being metal, putting the roof on cut down on the heat in the coop quite a bit, due to providing shade from the sun.
