I did realize today that the back of the coop, which faces S/SW, is where the prevailing storms come from and that the floor would get soaked in a heavy rain. Since half of the back is cedar pickets lined with hardware cloth, that's a problem. I temporarily added some plastic on the back. Tomorrow I'm going to build a "storm window" to cover the area, removable, out of new 1x2's with new clear plastic to keep the girls dry. I may add a wider roof if I can find more cheap plastic roofing. But I think the storm window will work great! Our feeders I bought ate up too much floor space, so I'm taking them back. Then my husband said, "why don't we make it bigger and bump out the back?" And this from a guy who didn't want chickens!!!
