Guard Llamas...

...we think. Roy had a chat to the three in this field on his run this morning, and we popped back out after coffee - me to catch them in a pose and Roy to remove some fast-food rubbish on the lane that some inconsiderate person had obviously thrown out of a car...
The three were together in a field today, but we have seen them in amongst sheep, seemingly acting as a "guard". When I looked on YouTube, it's a practice that seems to have arrived here from America,,,
Who knew?
