I bought a lovely, large chicken coop for my baby chicks second hand from the feed store. I KNOW that I need more ventilation and plan to do it. I thought I would have you AMAZING people help me to identify what to do and where to do it. I’ve attached the pictures of my coop. Everything we do, we will do with hand tools and we are not too terrible handy though we can follow directions. The promised coop pictures. The only ventilation is in the windows (picture 1). I plan on putting windows in the door (picture 2) and on the back (not pictured). Any ideas? Thanks for your help!
