unicornis there was 2 other rhino births in the 90's one of the young was stillborn and the other survived a week before dying.they were both males.these 2 were the offspring of esther and parky.also after the birth of kitani and manyara the male(quinto)was moved to another collection and an unproven male was brought in.the same happened with parky and hence the rhino breeding program at chester zoo was put back.what i can gather the zoo had no real say in what happened with the proven males and had to send them to other collections.
