Our winters are not as fierce as some of yours. But here in the High Desert, we do get snow and it gets quite cold. This year, I am moving a couple of hens up to the (fallow) garden with a snug little hen house. I think they will have a blast and help prep the garden for spring. The garden is in a spot that is protected from the wind, so they should be warmer than usual as well. It's also a way for these hens (who no longer lay) to contribute.
