This is my first winter with the 5 girls and I am preparing for 0-30 degree averages in Dec, Jan and Feb. I covered the wire sides of the ground floor of the coop (only approx. 75% of it so as to provide ventilation) with plexiglass sheets to cut down on wind in the roost. I will soon place a heavy tarp over one end of the run to reduce snow in the food, water, coop areas and dustbath. I have been told the coop is small for five birds, however they have done fine thus far and have plenty of room in their covered run. I will trade their water out a couple times per day during freezing weather. I will not use electricity or heat and hope they will be happy and healthy. Any suggestions are welcome! We live in a neighborhood with a privacy fence surrounding our backyard. I am hoping not to see any predators. Saw a hawk attempt an attack this summer while the girls were free-ranging in the yard. Covered the top of the run immediately. Plexiglass covers the windy side of coop. Covered run under evergreens. Inside the roost.
