Hey yall, this is my first "winter" with my hens and I live in South Mississippi. My girls lay in a modified dog house with the opening facing the north but their roost is a lean-to with a slant roof and no sides. It has worked great for the Summer because its shaded and breezy but I'm worried about the winter. Should I board up their roost to protect them from the wind/humidity/rain/and cold weather? We might have a few 30 degree nights but I'm mainly worried about keeping the dry during the cooler weather. Any help would be great. Thanks!
