Well, it went from 50 degrees yesterday to a high in the low teens today, wind gusts up to 40 mph, and a wind chill around 0. We're under a winter storm warning, with snow totals expected to reach 5-7". With the high winds, this translates to a trace in some spots and 12"+ drifts in others. I knew our winters could be this way, so we planned for this when building the run that is attached to an old shed converted to a coop. This is our first big snow since building it, and I think we passed the test!
We put 6mm painters plastic around the run on the hardware cloth to block out winter rain, snow, and wind. There is a little ventilation at the top that allows a small dusting of snow to get in. The roof is covered by metal roofing panels, and there are 2' high base boards all around the run blocking any drifts that may form against it, but so far the drifts are forming away from it.
The silkies sleep in the coop but our guineas sleep in the run at night on the branches, so this extra protection is good for them. Due to the high winds and snow today, there was no ranging allowed, so the guineas had indoor recess in the run with the silkies. The guineas have been around silkies since they were tiny keets, so they've always done well together.
I went out after a couple inches of snow had fallen to see how everyone was holding up: (we still got 2 eggs!)
