There are 47 different sheep breeds in the U. S.
Wisconsin is home to over 90,000 sheep.
Not all sheep have wool.
One pound of wool can make 10 miles of yarn.
Sheep have no front teeth, but the roofs of their mouth are hard. This permits sheep to eat vegetation close to the ground and prevents them from pulling up plant roots.
Sheep have a split in their upper lip, with this they are able to pick the preferred leaves off the plant.
