My dad and I built an adorable coop using a pattern from a book. I love it to bits, but we dropped the ball on ventilation. We have two plexiglass windows that at present are not removable. They are, of coarse, not a standard size. I have some time in the next few months and would like to add appropriate ventilation. Our winters go down to about 0F and are summers are in the 100 range, I'd like to be able to open and close the ventilation. My construction skills aren't great and I'd like to keep the coop looking nice, so I don't mind paying for something pre-made. I just can't seem to find it on line. Our coop is sized for 8 standard breed hens, if that makes a difference.
Anyone have any tips? I keep reading about how important ventilation is, but I can't figure out how to do it while still allowing for cold weather protection.
