 Males will typically fight one another in front of a group of females before they mate with them, with the highest-ranking mare in the harem the first to mate.The gestation period for Chapman's zebras is around 12 months, after which time the female will give birth to a single foal.The foal is quickly able to walk with the rest of the group which is essential for its survival, as it ensures that the mother doesn't have to leave it behind for the good of the other members of the harem.
