My boy Chad will be moving on this year. He's pure bred, from registered parents, but not registered himself. (His breeder was dispersing her flock and I didn't need him to be registered.) He's a musket katmoget, and has the gene that allows the expression of colour from the mother's side.
I had only planned on using him once, but I liked his lambs so much I kept him on for a second year. I've run him on a mixed flock - some Shetlands, some other primitives, and quite a few crossbreds. His lambs have been shapely, and I've had lots of lovely colours to enjoy.
I'm up in Cumbria, though.
