Can you pull the plastic down a couple inches from the top to allow some ventilation, but not so much that it is creating a draft where they sleep.I have a question about drafts & ventilation... here's my coop. I have to laugh at how nice all those wood chips look on the side there.. I must have took this right after we put it down and before the chickens got to it!
The wind seems to blow toward that side window, so that window is covered with plastic. They roost right next to that window. The two front windows are not covered at all. But it seems like once the side window was covered there is no breeze inside, even if the wind blows at the front of the coop. My husband went into a big long explanation as to why the front windows don't need to be covered (I just remember that it ended with "It's physics!"). I've stood in there when it's windy out and it doesn't seem like there's a breeze. The only reason I'm questioning it is this is MY first winter where I'm making all the choices myself. My great uncle built these coops in the 60's.. now he used to cover all the windows with glass, but I didn't like that because there was zero ventilation in there. But he has passed away and I don't have him and his 50 years of chicken keeping knowledge to ask anymore. What do you guys think?
