I bought a small flock of 12 for the place I work as they wanted some rare breed sheep, and they were keen on aesthetics! However, they are a difficult breed to manage day to day (well thats what I find!)
They jump stock fencing, mains electric does not bother them, and they like to roam as far away from where they are supposed to be as possible! They dont tend to bunch as a flock when getting them in for any work they need, dont respond to bucket training, and very difficult to check daily for things like strike with the black fleece.
The lambs are fairly slow growing so really only ready to slaughter as hogget, and ewe lambs not ready for the ram as shearlings.
I can see why they are on the at risk register........ if you like hard work then great, if you want the easy life get a different breed!
