We don't typically get a lot of snow, but there's always the year that goes rogue! I have two of the Universal poultry pens from TSC, so a reasonably sturdy surface, but brooming off is still sound advice!If you use tarps, be sure they can handle the snow load.
My run is built with the metal frame of an unused green house. I put chicken wire over the top for some protection (hawks, eagles) and the tarp was over that. There is a 2.5' span between the poles that form the roof. I kept it broomed off every time it snowed, but I was still surprised at how much sag there was in the chicken wire when I took off the tarps this last spring.
