Hello Dougal and welcome from the far north west of England.

We're beef & sheep farmers (very traditional, low input) and keep pigs, choox, ponies and a jersey house cow on the side.
We bought some cheviot stores for the first time last year and were very happy with how they did. I still can't quite understand the Hill versus North Country type thing ... can you explain please?
We also have a few cheviot cross texel ewes; they're not the easiest to manage but they do have outstanding lambs.
We do need a new cockerel and we have been offered some scots grey hatching eggs (if any of our girls ever decide to sit this year...

) so an unrelated sg cockerel could be useful - where are you?
