I have read from many sources not to let your flock be subject to drafts, but that they need lots of fresh air. Our coop is situated with the door and windows (covered with hardware cloth) on the East and West sides of the coop. The wind here in Kansas, which everyone knows is blowing a lot of the time, comes from the North and South. Should I cover the windows on blowy nights? Last night I barely slept because I was so worried about them, but they were all fine this morning. So, what does one consider fresh air and what is considered a draft?
