Unheated but wind resistant barn so they were fine and bedding. Was a late snow storm and they were due for having little ones running around. Have done shearing a -20F and they did ok, no freezer sheep! The humans were down to t shirts and sweating! During breaks, sweat would freeze in the hair and be like beads.

Guess i got used to using 4wd from the inside, no hubs. Heck do not even do that for the tractor.
