The Konik was originally a wild or semi-wild horse held in Poland and Belarus. It is small in size. Koń is Polish for horse. Konik (konjiek) for little horse. The Konik is a descendant of the Tarpan, the wild European horse. They are imported from Poland.

Like any young animal, konik foals are also highly dependent on their mother. This also applies to a foal that was born two weeks ago in nature reserve Oranjezon. There was some doubt whether this foal got enough milk. A few days later the foal was suddenly in another harem. Particularly remarkable, however, was that the foal was walking with a mare from this other harem as if it was his own mother, and even drank that mare’s milk!
It turned out that the foal’s foster-mother was its grandmother.
