Just saw predicting to be below zero Thursday and into Friday, but we live in a small town and all our stores closed early to tonight (what few we have). I have a tarp over the run, for moisture, but I've seen folks say to wrap the run. I don't have anything on hand. At all, Should I keep them locked in their coop for safety against the cold until we can get plastic wrap? Anything I can use that may already be in our home to help with the cold? Trying to think creatively. Worried about them.
