Thanks again for advice, info and humour.
We have contacted trading standards who would only do something if we have ear tag details, which, as none of us are local, is proving a little difficult. We have one localish person who’s keeping an eye on the property and reported the sheep being back on the land in the first place. Not sure how good she is with a zoom lens as I’m pretty sure she’s not going to be great at catching sheep!
Not sure if the potential sheep owner (PSO) is just trying his luck to keep them on the land for free, or if he’s keen on a bonfire. Hoping it’s the former!
About to see if anyone had any luck contacting the PSO (Jeez, we’ve got acronyms now!), but doubt it as I’d like to think they’d’ve told me.
