In North Dakota & need more info on how to stop drafts & provide ventilation

[terri1nd]

I live in North Dakota & need more info on how to stop drafts & provide ventilation. We now have mostly Chantecler chickens due to a mid day raid of a coyote. Husband wants the chickens out of his garage (can't blame him). We have 2 hoop coops we have used for broilers in the past, as well as summer coops for the chickens, but now are combining them to make one large coop (we have 19 chickens at the moment). I'm trying to figure out how to help them through the winter & how to arrange everything inside. We have a truckers tarp on the top of a cheaper tarp for protection from sun & rain (at the moment). I've heard of huddle boxes & plan on figuring that out, but I'm kinda stuck on how to stop drafts & provide ventilation. For the water, we have a heated dog bowl we put the water in. I wanted the Chantecler chickens because they are bred to handle the COLD WINTERS, but I do want them to be as warm as possible so WE can rest easier.
I've seen all the coops & the Permanent Hoop Coop & love it, from what I can see of the details but the details I really need to focus on are not really shown, so I'm reaching out for someone to help me understand, what I'm not comprehending at the moment about how to stop drafts & provide ventilation.

My understanding is that the best position for venting is above the roosts, high up, so the drafts will not hit the birds. One square foot of venting per standard sized bird is recommended. (I have lots of ventilation for now because my hens are in an open-front rabbit hutch that I tarp at night and in bad weather. I need a winter solution, too.)

Thank you so much for answering this for me. I had asked DH & he was not sure on it either. This helps tremendously.
