Hey guys. Been watching the forums for some time and I finally built a new coop to replace my basic tractor. It is completed and now I am trying to determine if my design will provide enough ventilation. In the summer I plan to have the window and vent open all the time but as we approach winter I only am cracking the window on the front. I plan to install a light tomorrow but want to know if I should do change something for ventilation. Let me know what you think. Attached are some photos of my coop. Thanks for you help in advance.
