??>With three deep brood boxes there are about 60k bees (theoretically), and
the temps can still get very warm during the day.

I doubt in NH right now you have 60,000 bees in your boxes unless you have
been doing what we do which is feed syrup & patties since February and the
three boxes are not as effective I have been told for above formic use. I
have been *told* that removing one deep and using two during spring the
treatment works best but I have never personally tried to treat three deeps
with formic.

We seldom find a hive in Missouri which will not fit in a single box in
early spring. We reduce down and then begin the process off getting the bees
to fill two boxes. Three brood boxes works for some but not for those moving
bees around. Actually some research has said that its all a prolific queen
can do to keep 10 frames filled at peak season but I prefer two deeps as
less swarming issues and more room for winter stores.
