You could of course buy in Lleyn's, a very manageable sheep ( providing the breeder is good) and the lamb/mutton is exquisite. There are also a few breeders with the Lleyn sheep society which are based in Devon, so that could be something to look into for the future. I myself bought in a few sheep to start with and haven't looked back, they're easy to handle, very tame and quiet sheep and follow you around like a bad smell after the bucket ( plus they're good milky mothers and easy lamber's producing twins and sometimes triplets, depends if you flush em or not). The market also likes Lleyn for the length of the carcass and the confirmation. If you do buy any in for breeding make sure you buy good quality stock and from a reputable breeder, remember good ewes from good flocks live for a long time. I would advise buying from people who use a full pasture based system and ones which lamb outdoors, as those will be the better of the lot.
