Was standing in front of my coop fan the other day "testing" it (mid 90s plus very humid), and for some reason I started wondering whether it would "cool" off a chicken the way it cools me off. I mean, a fan makes humans feel cooler because it helps dry our sweat, therefore we feel cooler. But chickens don't sweat do they??? So is it even making a difference to my chickens, just moving the air??? Do you see what I'm saying? Of course a window fan can pull in cooler air if it's cooler outside the coop than in, but what if the temps in and out are the same?
