ALMOST everyone here was inside during this recent polar vortex. The windchill was between -40*F and -50*F. The horse, however, left his barn and feed and went up the hill INTO the wind to eat in the pasture. Hardy creatures! But he had a choice of where to be.
The chickens also had a choice. They had a heat lamp in their hen house. They peeked out their sally port and decided that the weather was too unpleasant. Almost all of them chose to stay inside.
