We had nearly identical weather. Put the goats and chickens in the basement near the drain pipe. We've kept track of this method in the past and know that they raise the temperature significantly in that area so that worked well. Louise (our goat) just about dragged me inside and ran straight into her crate. She always knows when the weather is coming in. Then we all holed up. Zo slipped at some point and strained something in her leg. Three days of recovery but she's back on track.
We saw something taped to our front door the second day. It was the inventory of our livestock which is required annually by our animal control officer. The idea is that she checks the animals and their accommodations then files a slip with the federal government so they can keep track of disease and potential problems. I seriously doubt she went into our basement so she never did see them. It was weird that she was doing that during extreme cold so hopefully she wasn't in our area because somebody's pets were in distress.
