The Mayo Blackface Mountain Sheep, a Resilient breed

About the Mayo Blackface breed

The first Mayo Blackface arrived into Killary Harbour in 1850 on a ship sailed from the Scottish Isles of Lewis and Harris. The sheep were transported by Captain Boswell Houston who had leased some 40,000 acres of West Mayo land, bringing with him a group of shepherds who have left behind told tales of rams disappearing by night to mate with native sheep.

These newcomers would later go on to form the tough genetic makeup of the ewes that graze our hills today. A breed now nourished by a health of herbs and the spray of Atlantic sea air, the Mayo Blackface is seen as a sort of ‘ecological tool’ that helps to manage the rugged hills and ultimately improve the biodiversity of the areas in which they roam.

The life of an Ólas Hill Farms farmer

Our Ólas Hill Farmers’ year begins in autumn when the rams and ewes are let run together, continuing through to the busy lambing season in spring, before the lambs are reared and ready for market during the summer. While their workload is continuous, we always try to help our farmers make a little room for everyday life.
