East Friesian Sheep are a medium sized breed the full grown ewes generally are around 150 lbs rams can be 250 to 300 lbs. But don't let their size scare you every Shepard that I have talked to has said that their personality is more like a big dog. And I agree my ewes and rams will follow us around and want to be pet. Of course we all have a few odd ones but most of them can not get enough attention. EF the best milk producing sheep. They are also good meat sheep ram lambs can easily grow to 100 lbs in 3 months. But if you are looking for a wool sheep these sheep might not be the ones for you. They only come in black (natural color) or white and their wool is a little more coarse than most people look for in their wool sheep. Their wool is great to use for rugs and needle felting. It spins up nicely but it is a little rough. Neither rams or ewes have horns.
