.............I hate to be a pain but you really do need a commercial movement for a sheep if 2 or more..........I have spoken to just about every DEFRA official and State veterinary service vet I can.............main office in Chelmsford.
An officially licenced transporter is the only way...........I could take Merinos (a Ouessant ram) in my van as there was only him, and there is a loophole in the TRACES system, but if 2 or more its a whole different ball game and even though I am licenced to transport across GB I am not allowed to bring my trailer over to France and then return with livestock as I am not licenced for journeys over 8 hours, none of us are.........This is why we imported 17 the first time as it was the only way to keep costs down........and whilst not from the top French breeders every one imported is small and sound in conformation etc....................no point importing poor stock!
I will add that the cost of buying and bringing 17 sheep from Brittany is half that of buying stock in GB where a ewe is approx £350
