My chickens are doing pretty well. We have tons of snow in Mass 2015. We plastic covered the run, close the door to the coop at night, and bring them snacks on a daily basis. There have been waves of 'stages' the chickens have gone from not laying to laying well. My plymouth rock stopped laying a few weeks ago, but the leghorns began laying for the first time simce November. The red is consistent laying still, thankful for that. It's actually kind of warm today, relatively.
