The Abacot Ranger duck breed is dual-purpose duck breed which originates from the United Kingdom. The breed's bloodlines come from the Khaki Campbell and the white Indian Runner drake. Abacot Rangers look similar to the Khaki Campbell except are a bit larger. When they are eight weeks old, males and females can be distinguished by their bill color; male bills turn olive green and the female's bill turns a dark slate color. The color of their feathers change during breeding season.
