Chillingham cattle are a breed originating from the Chillingham Estate in Northumberland, England. They are known for their unique appearance and conservation status as one of the oldest and purest cattle breeds in the world. Chillingham cattle are small in size, with a white coat and distinctive hump over their shoulders. They are also known for their wild behavior and strong survival instincts, making them less suitable for domestication compared to other cattle breeds. However, they are highly valued for their historical significance and are protected as a rare and endangered breed.
