Horses live in herds primarily for safety reasons, as well as social, resource, and breeding benefits.
Safety
Herds protect against predators, provide early warning systems, and increase vigilance.
Other Reasons
Horses are social animals that bond through grooming and play. Herds share resources like food and water, and herd dynamics facilitate breeding.
Herd dynamics are complex, with hierarchies involving stallions, mares, and young horses. While domesticated horses may adapt to stables, they retain natural herd instincts.
