How are the birds handling the cold? I left mine in the coop this morning where there’s no drafts and it’s a little warmer. I just went in there and it’s 10° whereas the run is 0° and it’s still -3° outside. Maybe around noon I’ll let them into the run when the sun is beating on it more. The spruce trees on the south sude if my yard have gotten tall enough that they block the sun this time of year.
I mean it doesn’t get a lot colder up there than this since you don’t really radiate. I’m sure your area has done -20s with wind, but like Will said, normally these temps with these winds yield mid -30s on MWN which is pushing their extremes.
