My birds will avoid the snow at all costs! Ive gradually expanded my coops and runs because as I've added birds, they separate into separate flocks. I have 64 birds right now and I have 20-25 that sleep in one run, ~10 that live in another one, 18 that live in a third, 4 roos in their own coop/run area and the rest split between 2 coops. Except for the boys, all coops and runs are in an ~1/4 acre area. They all have space to avoid each other, but it's always interesting to see how they end up mixing up as they grow. I live in the northeast US and it's pretty darn cold. I use plastic greenhouse panels around the runs in the winter. My stupid birds will stay in there year round, despite the coops being 12 degrees warmer, on average. The panels are easy to install. I have metal runs so I punch holes in the panel and zip tie them to the run. I then use greenhouse tape to seal the seams, but leave a small area at the top uncovered for ventilation. I've included a picture to better show my general setup. With your wooden run, you could easily screw the panels over the wire giving the birds more insulated cover.
