This is ingenious @frazzledfozzle ! Can you please just explain it a bit more thoroughly? Such as; do the two (now) singles stay at the same site, do you put a new mated queen with the box taken off, do you equalise them somehow...? Cheerswhat is your hive configuration ?
where I live we don’t get a good nectar flow.
if we ran double brood hives we wouldn’t get a crop to harvest.
the bees would generally just fill the top brood box with honey and not bother going into the honey boxes.
so come honey time we split the doubles into singles and put a couple of honey supers on .
The bees will fill them and it’s one for us and one for the bees.
