Noteworthy about the double deep, side by side, two queen hive is that
it has become a popular configuration due to promotion by Dennis van
Engelsdorp (Pa. State Apiarist) as a handy setup for drone trapping
Varroa control.  Side by side brood chambers are supered in the middle
of the brood chambers, with half covers to close each side, and a full
cover over the supers.  The drone trapping Varroa control aspect comes
from keeping a drone frame under the half cover in each of the component
hives.  The beauty of this configuration is ready and easy access to the
drone frame without having to remove the honey supers!  Last update I
heard was the control achieved did not equal that of a two drone frame
removal regimen but the data was preliminary.  Has anyone heard a
current update?
