Our run is a huge 50 x 30 with our coop inside. My question....can I reasonably cover the area over the coop and a small adjacent area of the run so rain and snow will not be problem? Since the weather has been so hot and humid I'd like to leave the coop window's and doors open but with our rainy days the inside would be get wet if I left it open. I am thinking a tarp from the hardwood store anchored at the grommets to our hawk proof netting would work, but don't think this would work with the potential heavy NY snow's we get for the winter. Any suggestions?
