Good morning! It was sunny and clear, but it's clouded up now.
The first winter I had my chickens, I kept the snow out with a heavy duty tarp over the metal frame I had for my run. I covered the roof with chicken wire, then put the tarp over that. The wire helped support the snow load on the tarp. I broomed it off in the morning to keep it from piling up.
The metal frame was from an unused greenhouse. The supports were 2' apart. I could reach the peak with my push broom to pull the snow down. The tarp was slippery enough that the snow didn't stick well to it.
