Mandai has 0.4 Nile Lechwes under its collection. 0.2 are housed with the Thamins at night safari while another 0.2 are housed at the zoo's giraffe exhibit. As of current, the two females are only released into the exhibit for a very short period from 8.30 to 8.45 during their den cleaning before they head back to their back of house. The two females are extremely skittish.
A majority of the hoofstock do seem to be in non-breeding groups or down to a few individuals namely the guanaco, ibexes, anoa and nyalas but they do have another 2 lechwe at Night Safari. Guess this sort of a temporary acquainting period before they're on permanent display eventually
@Zooish the night safari herbivore team is looking into getting a male on their end, not sure if the females at their side is younger than the ones here
