Our winter coop was not going to be done before this frigid weather came in and we go out of town. So friends gave us a wooden playhouse. It is 4 x 4, the main part is about 4 feet high, with a peaked roof that is about 6 feet high. It is on our back porch.
There are three windows. They are 9x9 and 28 inches off the ground. The front window is a normal flat square, the sides are diagonal diamond. Even if the windows were completely boarded up It is not air tight, but the section of the porch it is on has plywood around it to help block wind and snow (and we've made the back porch into a covered run for them). What I am wondering is how much of the windows I should board up and how much leave as a vent with mesh over it. We have 8 hens and a rooster.
Thanks for your help.
