I ran across this recent publication Low Input Lambing and Kidding, by Cornell University and found it to be really refreshing reading. It had my keen interest from the introductory paragraph describing one impetus for the study:
During a recent sabbatical in New Zealand, Dr. Michael Thonney, who is director of the Cornell Sheep Program, had been intrigued by the relaxed attitude lambing of New Zealand pasture based farmers toward lambing.
It goes on to say that their Extension program gets a lot of inquires from experienced sheep and goat farmers who are not seeking help with the day-to-day basics of small ruminant husbandry, but rather, how to make it be less labor-intensive. This white paper is an attempt to offer advice on that subject, based on a small study.
