I hear this a lot and I know it is important. We bought a pre-made chicken coop and it was homemade. The previous owner (maker) had 12 chickens but none of them survived past the first year. (I don't know why.) It is not the best designed coop... I am worried about when the winter comes. I am looking into insulating it. BUT... my question is.. it needs ventilation but can't be drafts. This might be trivial, but could you post pictures of what is meant by ventilation? I *think* I know but want to make sure. Thanks!
