If you plan to breed, buy a few ewe lambs this year. By the time they are ready to breed next autumn, you'll all be best chums and you have a year of sheep care under your belt before you lamb.
Get Tim Tyne's The Sheep Book for Smallholders - if you can't get on a course, it will help enormously. I think there is an active smallholders group in Dorset that might eb able to help with training.
