Coming from a sheep, beef and deer farming background, Duncan's shift into the dairy industry was the result of an opportunity on his own account to undertake a dry stock to dairy conversion. As Managing Director of the company Duncan project managed the conversion and then continued to run the dairy farm for a further 3 years following the conversion.
