>Drifting is less of a problem than people make it out to be anyway.
Unless varroa, viruses, nosema, AFB or EFB are present. Then drifting can
be a major problem. I consistently observe colony mortality to be grouped,
strongly suggesting that the parasites causing such mortality disperse by
the drifting of bees to adjacent hives.
