The first picture is the front of the coop and faces south. We keep the girls' door open all the time. The human door and the two window stay open unless it is cold in the evening, which it has the last three nights. There are two long open areas on the east, north and west sides and a window each on the north and south sides. The 5th pic shows the east vents in relation to the nesting boxes. The 6th shows the small window on the north side closed and the next pic shows the roosts in relation to the west side vents. Last pic shows the south side with the larger window (closed) and the chicken door (open) in relation to the roosts. Is this adequate ventilation, do I need to do any more? Thanks in advance!
