For my hoop run....
PVC pipes attached to cattle panels with zip ties, heavy gauge plastic over the top and clips for greenhouse use holding plastic to PVC.
I can raise and lower the sides easily by unclipping the bottom then holding the raised plastic up with the same clips.
Seventy mile an hour winds did pop a few clips off but not enough to compromise it.
I do clear the snow using a sturdy broom. There is a space next to the coop that is 6" wide left open across the whole hoop.
Second winter with the same plastic and holding up well.

but we do get ALOT of rain
and warm humid days that intermingle alot. Came up with this idea; open air Chicken House with shower curtains that I can close up when needed, rope for when the Trade Winds blow. January will be 3yrs & I have yet to replace shower curtains.
