I have a 12 x 8 prefab building as my coop. One window and double doors, so plenty of ventilation. The problem is that, when it rains, the rain blows in and the floor gets wet (not the nests or roost, due to placement). I would like to install something like shutters/louvered closet doors over these opening to keep the rain out but still have ventilation when it's hot. I usually leave the window and doors open and have wire over the window 1/2" and a dog kennel wire door over the double door opening. Just wanting ideas to keep the rain out. I also bought louvered panels like over your furnace filter that I plan to put on the opposite wall but haven't done it yet, mostly for circulation when it's hot here in the South. Does anyone know if you can easilly make louvered covers? I have tools but have no plan for how to go about creating angles.
