雖然公山羊羔經常因為無法產奶而被淘汰，但有時牠們會被閹割，並作為「閹羊」留在羊群中。這種脖子上掛著鈴鐺的「領頭羊」通常是羊群的領袖。

Although the male goat kids are often culled because they will never produce milk, they are sometimes castrated instead and allowed to remain in the herd as a "wether". With a bell around its neck, such a "bellwether" is usually the leader for the rest of the herd.
