Ours aren't registered either. We just wanted shedding sheep large enough to produce a decent lamb carcass when crossed with anything! One has a wonky horn so she wouldn't win any prizes but is extremely placid and happy to stand for hours having her chin scratched.
We also have Soays which tick the pretty box 
Going off topic I know but what do you do with the Soays? Thats what mum asks me. Currently way understocked but under or over, they all (apart from Tugger) need to earn their keep via meat or lamb sales at auction etc. My Shetlands, to Dorset Down threw really good animals, breeding and eating but I don't think I'd put a DD on a Soay. I'm no lambing expert and the nearest vet is 20 miles when they are in this area.
Even Had the privilege of a c-section this year. My poor back and knees! Why they can't knock the ewe out is beyond me. Gas, cut, pull out, stitch up revive..... Easier by far!
