7 years ago I did a 2-day course, "Ruminant Health for Smallholders", with Kingfisher Vets, Crewkerne. Their aim was to give smallholders a good understanding of how to know your sheep (or cow) is healthy, and keep her that way, and when to call the vet and with what information.
It was one day classroom and one day on farm, the latter giving practical hands-on training in handling sheep (and cattle), trimming feet, inspecting teeth, etc. It might be worth contacting Kingfisher to see if they are doing any courses now; I think I was on their first one. There was a grant, I think, for people who had a holding number.
