Yes, my question is do I have enough!! I'm sure everyone is tired of hearing that question. Here is my coop: I came out the other morning to let them out, and the glass on the people door was fogged up. It has been getting to 32 and sometimes below the past few nights here in NJ. The left side is their coop. Above the window on the left is open ventilation, running the whole length of their coop. This is the wall just inside the people door, to the left. The upper part that is not painted has been cut out and has hardware over it. Also, all along the top edge of this side and the opposite side is open too. I clean their coop about every three days. Did they fog up the door? I did not notice if the windows in their coop were fogged up. Do I need more? Thanks!
