Climate could be a possibility, or the way the bees  are kept. When I first
had bees, I had chalk at low levels. I also had  condensation in the hives in
winter, due to the damp British climate. I put the  hives on mesh floors, which
eliminated the condensation, and also,  ince=identally, eliminated the chalk,
at least in that strain. I've no idea  whether dampness could be a factor in
the sort of levels of chalk we're hearing  about here, but it might be worth
considering.
