I have a plywood coop with shed roof without much of an overhang and I have several large and small hinged flaps (except they are all hinged on the bottom so they can be left totally open easily) with the holes covered with hardware cloth on the inside. I had hoped that rain would not blow in the windows and last night it was raining so I only left the highest and smallest vent open. This morning a third of the litter in the coop was wet - all around that vent. So I need to figure out a way to keep water from blowing in even with then flaps are open. I have searched on the Home Depot web site and checked my local hardware store but I can't find any mini awning type drip/rain covers. Does such a thing exist? Is there is an easy way to build some sort of covers for these windows?
