40 breeding age females elephants.
4, are pregnant to my knowledge
-Umngani
-Vasha
-Mbili/Renee
-Ivory or Kubwa

Does anyone have any information on whether any of these females are pregnant, or hoped to become pregnant?
*Note, I know the recomended first time breeding age is 24, but I went up to 25, and also included past breeders under 40 years old.
