The Social Hierarchy in Herds of Domestic and Wild Horses. Within the band there is a hierarchy with one mare co-leading the band. While the stallionâs role is to protect the harem from predators and other stallions; the dominant mare leads the band to shelter, food and water.
If a stallion is not to be used for breeding, gelding the male horse will allow it to live full-time in a herd with both males and females, reduce aggressive or disruptive behavior, and allow the horse to be around other animals without being seriously distracted.illies usually soon join a different band with a dominant stallion different from the one that sired them. Colts or young stallions without mares of their own usually form small, all-male, bachelor bands in the wild. Living in a group gives these stallions the social and protective benefits of living in a herd.
