Young wild stallions are usually booted out of their birth band between the ages of one and two. Except for rare occasion, horses are pack animals, and prefer to belong to bands, so these stallions will form stallion bands, made up of all males, until they can win some mares and form their own band. Some stallions are never successful at this, and stay in a stallion band all their lives. These three are part of a newly formed band of five. The stallion band is where they learn how to fight, which is necessary if they ever hope to steal a mare or two from another stallion. At this moment, they were more concerned with getting away from me!
