I have one that is a permanent resident in the henhouse! But it's hot in there so I am thinking of having dh put in more ventilation in the back so there will be some airflow. We have an A-frame house built into the coop that he thought he would put some square holes in and then I thought we would use chicken wire and screenwire over the holes. There are some round vents but not enough and he is going to square up the henhouse when he gets the chance but he doesn't have time yet so this would be a quick fix. What do some of you do to keep the girls and guys comfy in the summer?
