One thing to consider with ventilation before you start opening everything up is how high your winds get and from which direction they usually blow in the winter. I can’t do open sides with hardware cloth here. We get icy winds (we have had up to 115mph since moving here and 20mph winds is a normal average day here) that blow from every direction and when the snow dumps it dumps. When we first moved here there were several 6x6” mesh covered opening on the barn. I kid you not every snow storm we had 2-3ft of snow piled inside the barn right under those openings. The lean-to that I converted to a chicken area with pens had a 2” eave gap. Same thing imagine a 60’ long building with 2-3ft of snow piled inside the actual building all along that entire 60’ side of the wall. I had to close everything up and install industrial grade agricultural ventilation units in my chicken area. Now before we moved here I had an all hardware cloth open air coop. Big change and adjustment, but something to consider.
