Wild horses and domestic horses are genetically the same. Roaming freely, living in herd groups, and foraging for feed and water are all
actions natural to horses. The majority of stabled and confined horses would adapt to a free range environment if given the opportunity.
Even the new foals that horse owners often over-protect are quite capable of stamina and social interactions from the first hours of birth.
The first day for this filly was filled with roaming surrounded by herd mates, and varied terrain. She is quite content after a full day of life lessons, resting on a hillside with her mother standing guard.
