Hi there, we are not far from you in Keith and we have a small flock of Castlemilk Moorits who have proved to be really low maintenance.
They have lambed outdoors ( although last year we brought them all in for a change as the cows were out of the barn ), they have really good feet, they've not been prone to illness, hardy in the winter and they seem to do well on poor grazing. They also mix well with our horses if we need them to share a field.
Obviously we are biased though
If you want to come and have a look, just drop me a pm.
Regards
Mark
