Icelandic sheep are super interesting! They were dropped off in Iceland about 1,000 years ago by Vikings.
There are no predators, so the sheep are turned out into the mountains for the summer months to forage for themselves. Every fall, the shepherds and their families bring them home in a communal effort called Rettir.
Here’s a beautiful video of the process. Watch for the sheep at the front of the flocks, leading the way. These are called Leadersheep, a line of Icelandic sheep that are a little bit more intelligent and guided by their instinct than the others. You will also notice the beautiful and sturdy Icelandic ponies that the shepherds are riding.
