I'm wondering if you can tell me the best spots to put ventilation in this coop ? Let the cutting begin on Tues. and I wanted a game plan before then. Open to any suggestions. I will be adding a roost bar over the chicken door to the run. I have 1/4" hardware cloth to cover outside and in the vents. The leghorn is halfway in and out of the chicken door to the run, he is blocking it and you can't see it but that's where it is.
