That's interesting Sally. All I see in the fields around here are Texel, Beltex, Blackie, Mules and the occasional Suffolk tup.
You're probably right - but it would take quite an experienced eye to distinguish a Shetland X or 1/4 Shetland commercial ewe from one that didn't have a bit of primitive in it. If I get a chance, I'll try to get a pic of some of the part-Shetland commercial girls we have, along with some that don't have any Shetland in the mix - they really don't look very different.
P.S. Want to buy some mad loaghtans?
Twice a day every day at the moment, I find Pricket and her Shetland x lambs, and I think how much I like my Manxes, what good mothers they have been and are, and wonder whether I might get some more...
So the only issue is how many sheep I have - I already have 16 lambing this time, 5 ewe hoggs to join my little flock next time, and two ewe lambs out of 2 lambings this year so far that look like I'll want to keep them on... I was only supposed to have 20...
