I fully understand that a coop should be well ventilated, even in the winter months. I also understand that it shouldn't be drafty. But at what point does well ventilated become drafty? Last week I found a roll of 1x2 welded wire that had a mouse nest in it. My first thought ... "now, that's well ventilated nest". As I dragged out the roll, my second thought was ... "but what a drafty mouse house". I've been plugging seams in the coop but am not sure if I should tightly seal them all or not. Our coop does have a window that is always cracked for ventilation. How do I know if it's putting too much draft on the ladies? Ever grateful for your thoughts.
