I'm upset with myself. I checked the 10 day weather forecast yesterday, and it said tonight's low was going to be 52. I checked when I got back from the coop, which I did not put the tarp on the front side, and it said it would get down to 38 tonight. I checked a little bit ago, and it said 32. My daughter called to tell me they are now saying on the news it will be lower than 30. I would have closed the front side in, if I had known. By the time I found out, it was too late for me to go back, and do it. I am praying my chickens don't freeze.
