Building a sheep shed

 I have begun building a sheep shed. We are planning to get 2-3 pregnant sheep in January and this will be their shelter from strong winds and rain'n'snow. Apparently the land-race sheep called Spelsau we are to get are outdoors even when its rainy or windy but still they should have a shelter in case they need it.

So far the structure is up and the roof is on. I am using reused planks.
