A Happy Horse Is A Social Horse

 A horse very seldom roams alone.

Wild horses generally gather in groups of three to twenty animals. The stallion leads the group, which consists of mares (females) and young foals. When young males become colts, at around two years of age, the stallion drives them away. The colts then roam with other young males until they can gather their own band of females.
