We are in central florida and it is hot. I put ventilation in my coop but when I close it at night I don't feel they have enough air movement really. So my next coop is already in the planning so people that have very open coops with hardware cloth in the window, what did you do to make certain this is secure enough to protect your birds? I want this as open as can be but safe as we have neighbor dogs and hawks and snakes and coons that have already visited.
