No, it is just a breed.
No
There not wild if that's what you mean. If they live with others of the same breed it's because the owner has more than one Rocky Mountain Horse.
my family has never owned a Rocky mountain horse but we have had appaloosas, Quarter horses, Thoroughbreds, Oldenburgs, Shires, miniatures and a few others others and we've operated boarding stables...
