Obviously this is my first winter with chickens. As of last night it started snowing. I now have a couple of inches of snow. Right now my chickens are in a small coop til I can get them transferred to a larger one. They are free/open range and I always let them out daily to feed plus I given them a large scoop of a 14 grain feed twice per day. Do I still let them run around in the snow? or just feed them extra and keep them cooped up? I planned on only keeping them in their coop when it is very cold, is that the right thing to do?
