I was rewatching the E3 gameplay demo and I wonder if offspring will stay close to their mothers or the herd (I know that with some animals the care is divided amongst the herd, like elephants). I wonder this because sometimes the babies seem really far from the adult animals while in some other scenes they do seem to follow and be close. So was it a coincidence the babies were just close (because of a feeder or water source) or was it game mechanics. I really do hope they stay close to their mothers (though sometimes they could roam further) as this is very basic natural behaviour and something I remember missing in zoo tycoon 2.
