Hello! I am from Southern MN! I have 4 hens and a chicken tractor. I am wondering what other people in MN do with their small flocks through the winter. Do I need to try to keep snow out of their run? I want them to be able to go outside on nice days but am worried that we will have another winter like the last one I can move their tractor to a place where I have access to electricity for those really cold nights but I'm not sure what to do with the snow. Any advice is appreciated! Thanks!
