I have to admit I am not a lover of goats, never have been. Jeremy the Sheep Guy on the farm has reformed me. His goats do a great job along with the electric fencing keeping the coyotes away from the lambs. His theory is that multiple male goats with the sheep are the answer. They take their job of protecting the sheep very seriously. They do not get out which was my greatest concern. I suspect that he has trained them well.
