Controlling wild goats is proving tricky in Scotland's border country. While herds can damage trees and outgrow their food supply, these fierce yet endearing creatures have a place in people’s hearts, and they are believed to be a link to our Stone-Age ancestors. As different landowners carry out their own culls, there are fears of a devastating impact on the population. Richard Baynes finds out how it's hoped herds can be controlled, but kept healthy.
