Baby horses get separated from their families all the time, sometimes in a disastrous manner. The foal in this video was spared that terrible fate. A driver stops in order to help the foal in this video, who was previously just lingering in the street. It is possible that the foal would have eventually suffered a road accident.
The foal is very skittish about being approached by a human in any capacity. However, in this case, those feelings were unwarranted. There is a railing that is separating the foal from the other horses, and the foal had to be lifted up bodily in order to be reunited with them. Fortunately, the stranger in the video was able to do that with no additional assistance.
