It was 2 degrees below zero last night, so of course we were worried about frozen water pipes. But not where you would expect. The barn water pipes never freeze up. We have an 1890's tie stall barn but the water never freezes up in there. During the winter it is usually 40-45 degrees in the barn and the air moisture level stays acceptable since we have put in good ventilation. So we are fairly comfortable doing winter chores in our barn. And the cows are very comfortable, too. Of course, if it get down to 20-30 below, the temperature in the barn does go down to 35 degrees, but at least it never gets below freezing. So when the temperature drops, we don't worry about the cows' water. But we do worry about our house! Steve's folks live in the farmhouse, which doesn't have any problems. However, we live in a house up the road that was originally built as a summer camp. So, as you would expect, there is very little insulation. And there is no cellar, so the water pump and pipes are in the dirt floored crawl space under the house. Therefore, our pump and water pipes freeze up, a lot! We have tried everything we can think of to stop this problem, but there is only one thing that works. We have to leave the water running a little bit in the kitchen sink when the temperature goes down to 10 degrees above zero. It sure is a waste of electricity and water, but the alternative is dealing with frozen pipes. And that is no fun at all! So, although there are challenges associated with dairying during Vemont winters, our biggest challenge (frozen water pipes) isn't even related to farming!
