Congratulations, you've picked a delightful breed

They have Castlemilks, among other rare breeds, at Palacerigg outside Glasgow. Still quite a way from you.
There are at least two TASers in Scotland with Castlemilks, no doubt they'll be along to say Hi

shortly.
I'm just over the border in England but north of Hadrian's Wall (just), so quite a long way from you! I had 4 Castlemilk wethers last year to see if I could cope with primitives here. They did brilliantly and I absolutely loved them. They're in the freezer now and I have two Castlemilk ewe lambs bossing me about now

I've started spinning since getting the wethers, so now I choose my sheep for their fleece as much as for the breed, so I also have 2 Manx Loghtan gimmers and 2 Shetland x Castlemilk ewe lambs, one of which has a touch of Blue-faced Leicester in her so a very soft fleece

We can't manage a primitive tup here, so I won't be breeding pure, so it isn't an issue mixing up the breeds for me.
