I do not think the male calves were sent to Rum Creek or White Oak, might have been private as a good number of male calves from the program have been allowed outside interest.Great news, I've been waiting for this for a while! Also, ig this confirms the three 2017 born males have left, they probably went somewhere like Rum Creek or White Oak since no zoo has announced their arrival.
Of the 26, 14 have been female and 12 male.
