My chix are rarely in the henhouse during the day -- they're outside. I have posted pix before of the cool former hunting building I got -- it has "windows" that I covered with hardware cloth -- they have plexi covers on them, which I keep closed in wintertime: But the plexi was crappily done by former owner, doesn't seal out drafts well, and is falling apart. So I can either make new covers that are plexi OR I can just make wooden covers. In summertime, they will be open to allow airflow. In wintertime, closed (and yes, there IS ventilation!). It would sure be easier to just make wooden covers w/ no plexi! Does it matter that this means it will be pretty dark in there?
