Ok, I've been reading a bunch of threads on ventilation and I see that 1square per chicken is necessary but I have a very small coop so I can't see how that is possible. I have 3 girls that share one perch. In the one picture they are facing the small window, it's made of plexiglass and it caulked in there. Above that there is an opening that has hardware cloth on it. I was worried that would create a draft so I attached a piece of wood to the outside of the coop at a 45degree with the wide part of that angle up allowing the humid air to escape but the keep the wind out. To the left of them is the attached run which is covered with plastic. The pop door is almost under them and I've been leaving that open. Above the door there is a 4inch by 10inch open section for ventilation. The humidity has been up to 68% the last 2 nights with a temp of 45 degree. I can't figure out where to add more and keep the draft out. I'll attach pictures form my phone in a minute. Please help!
