> If you split a hive with 30,000 bees at the right time and you use some logic to your splitting your odds are pretty good. The failures are more to do with getting the virgin queen mated and back safe.
So ensuring there are eggs/young larva in each split does nothing to increase the odds of that split successfully raising a queen compared to a 'willy nilly' split of not even looking at the brood frames? Really?
If the split bees have no eggs to raise a queen there is no point worrying about mating success rates!
