My coop is my barn.I'm sorry...I must have missed the pics of your actual coop but I saw parts of your barn. I've found that ventilation that starts at the bottom and moves air up and out of the coop seems to be best. I think people get confused about the whole ventilation issue and start worrying about "drafts". Drafts are the worry of those who do not understand how animals live and thrive. A wind blowing directly into the coop at the place where your birds roost is a draft...a wind blowing into other parts of your coop is ventilation.
Here's an analogy: Say it's one of these 55-60* days and the sun is very bright. You are driving your car for a long distance, and the sun is making you too hot, but not hot enough to warrant fiddling with the AC~ but you really need some cool air. You don't want to roll down or crack the window on your side of the car...too much cold air where you be. So you crack the window on the other side of the car and it's just right for cooling the air in the car without ruffling cold air through your hair and on your face. THAT'S the idea of ventilation.
There are people out there copying the open air coops they used to build way back in the day up in Wisconsin. Almost one whole wall is open to the elements, coop covered in snow a foot deep and it stays all winter. No frostbite, no specially chosen small combed breeds, no heater or light. Just cold air and chickens roosting on the opposite wall.
Second picture taken when this part was being used for young chicks and silkies. No heat lamp now. Would the ventilation go through the rafters? I believe that is how I understood it from Fred.
There are 5 windows total. I could open a couple on the end, as the breeze does not come that direction.
But I could also leave the middle window open on the left.
Also, there are many little slots along the walls. I think that has minimal breeze, but still allows fresh air to enter. Am I right?
