I'm concerned as well. I have wind blocked off on 3 sides of run. Considering blocking 4th side, to hold in heat, I may do that this morning. I added 2 bales of shaving to run. I bought those simply because (after 5 inches rain ) all my leaves, litter etc... in yard IS STILL WET. I'm also worried about temp dropping, forecast says expect it to drop 30-40⁰ in an hour. That's drastic. I've seen it happen before, but not often.
