In a herd of wild horses there is usually only one lead stallion. At around one or two years of age, a colt horse is typically driven from the herd by the main stallion. When this happens, he will often join a herd of young stallions and other young colt horses, called a bachelor herd. I saw 3 bachelors near Pilot Butte in Wyoming living what can only be described as an exuberant life. Every time I saw them they seemed to be celebrating their freedom. They ran for miles together, bucking, jumping and whinnying the entire way. I was jealous. This little guy has a lot to look forward too if he can just keep out of the yearly roundups way.
