Shepherds tend their flock no matter the temperature and no matter the weather. That’s why shepherd’s huts used to dot the landscape in areas where sheep were herded. Sheep have heavy wool to protect them from the weather, but the shepherd usually bedded down in a small cabin. Those huts were either built on the edge of each grazing field, or they were on wheels and moved from field to field. The hut not only kept the shepherd out of the elements but it is also where medicine for the animals was stored. A sick or injured animal would often sleep in the hut with the shepherd.
So, that is not even a real argument.
Agreed. Shepherds are out in all kinds of weather. Beyond that, it was when the world climate was in the Roman Warm Period, even warmer than it is now with “Global Warming.”
Yeh. Like you would never get the job unless you did it 24/7/365.
