If you put plastic up, you may have to just put it half way up the run in the outside.
I use plastic sheets and they almost cover the run but there is a foot gap at the top for ventilation. I have to almost cover the whole run to keep the snow out, last winter the snow drift was almost up to the ventilated area.
