We haven't been above freezing since Dec. 24th. and only a couple of those days above 20 and several nights of -10+/-. We have chickens and goats. Chickens haven't done anything for them, haven't even closed their door - probably should have done that thinking back. Our big bucks have their 8x16 shed. They've torn the doors up, so I closed half of the one door that is left and closed the freezer vinyl where the other door used to be. Did move the young bucks to the baby stall in the barn (the yearlings have been moved to be with the big girls getting ready for the new babies). Other than closing the 3 doors at night, nothing special for them. Once the babies start coming, there will be some heat lamps used for babies if it is cold. Those are in hot boxes that the big girls can't get to or in plastic 55 gallon drums if they are in the kidding stalls. We also use the "Deep Litter" method of heating for both the chickens and the goats. From about October until April/May we don't clean the barns or coop. Just keep putting more straw on top of what is already there. The composting that starts help generate heat. In our barn, it is a metal pole barn, 1" foam on the inside, covered with OSB. The ceiling is open with a ridge vent. I looked the other night. It was -10 outside, but 20 in the barn. And without the wind, it actually didn't feel bad in their at all. Of course, all of the goats grew extra hair this fall, they knew this was going to be a bad winter. We also should have been kidding by now, they knew they needed to wait going in to heat so as to not put their babies at risk. Our babies aren't expected until Feb. 3rd.
