Here's why:
* Wild Ancestry: They trace their lineage back to wild horses, not domesticated breeds.
* No Domestication: They have not been selectively bred for specific traits, like a domesticated breed would.
* Independent Lifestyle: They live in herds and forage for their own food, exhibiting natural behaviors not typically seen in domestic horses.
Important Note: While not domesticated, Kiger Mustangs are often managed by the Bureau of Land Management (BLM) to control their populations and protect their habitats. This management involves things like roundups and relocation.
