We live in the Bay Area of Northern California, so we are used to pretty mild weather. We only have 3 hens. During the last big rain the inside of their coop was getting wet because the rain was blowing sideways, and my husband and I were out there trying to cover it with a tarp which kept blowing off in the rain. It was a huge pain and we ended up clearing out wet shavings two or three times to keep everything dry. Next week is supposed to be rainy and really cold (for us that means possibly down to 32F). We are going to proatively put some plastic over two sides of the three sided upper vent, and tape off the one door opening where most of the rain blows in. Do I need to do anything else? Are they okay at those low temperatures? Should I tape more of the venting?
