Pig arc as sheep shelters

I've been asked to post a picture of the pigs arcs we have that are used for sheep shelters, so I was out with my camera this afternoon, and in order to get the sheep into their shelter I had to bribe them with some sheep nuts.

So here are the boys, outside their shelter. You can see Hector in the bottom right of the picture with his one horn. He's starting to grow another horn, you can just see the bud

Just so you know whose in the picture, from the bottom right is Hector (looks like a panda), moving to the left is Archie, then Charlie, partly hidden is Cecil and then Angus in the shelter.

Now you can see how they look and why they are great shelters for the sheep
