far be it for me to defend jordan-12, but when he wrote "2 of the 3 female White Rhinos are also expecting the third is from one of the females born in 2008" what I think he actually meant was (with a bit of editing):
"Two of the three female White Rhinos are also expecting. The third White Rhino (i.e. the one that isn't pregnant) is a calf born in 2008 to one of the two aforementioned females."
Just what I was thinking - I never read that as all three rhinos were pregnant. When he says 2 of 3 are pregnant, the 3rd is the 2008 female, I see that as clear enough.
In fact, I see that as Jordan defending why SL haven't got all three pregnant - because the female is still too young (if that makes sense :s)
