I noticed a distinct difference between having the hardware cloth covered with tarps and having them open. The first day all seemed fine. On the second day the coop felt damp and had a stronger earthy smell than usual.
There was a small drip of water coming from a hole in the roof and one of the nipples on the water bucket was dripping as well. But that can’t account for the amount of damp in the air. I think most of it came from chicken respiration and feces.
I definitely need to proceed with caution when I start installing windshields over the three walls that don’t don’t already have them.
