We built our first coop this summer and I wanted to make sure that it had lots of ventilation, but in the recent below 0 cold and snow, it ended up letting snow in and my run isn't covered, so my poor chickens couldn't escape the snow! These pictures are of the ways we temporarily fixed the issues, but any suggestions for how we can build a permanent fix come spring? The covering on the vents is the thickest clear vinyl they sell by the yard that I could get at my local walmart. Just a yard covered part way on the big vents and completely the back vents (which were even with the chickens' heads while roosting.) Sorry about my finger in the last one. I couldn't see my screen!
