The brood is gone, but the empty cells were only slowly being filled. And the second super I'd put on with foundation was only slowly being drawn.
Bees have often hapit, taht they gather honey from chilly corners and move it in the center of hive. - I wait that this happen and I can rob honey easily.
In fact, a wet frame of comb I put in there after having extracted the honey two weeks ago actually seemed to have decreased, broken up and taken away by the bees.
Bees comsume a lot honey when flowers are gone but they have larvas.
Ok, so I've come to despise the queen excluder. Seems that's the common factor when the colony slows building comb in the supers.
Exluder is a barrier in the hive in many cases. That is why it is uncomfortable to use it.
I might have also discovered another problem the excluder causes. When I pulled the supers off, there were clumps of dead bees lying on top the grid.
Are they robbing bees?
What do you do with incomplete frames of honey when you pull the supers for winter?
before exracting I keep honey in the chamber where I have 2000 W thermostat heater with propel. After couple of days heater dry up open honey. If you keep waming on one week, honey will dry under caps so much that it is difficulta to exract.
Also i can put open honey to winter storage. It is same that exracted combs consist 20% of frame's honey. 2 kg honey in frame, and 400 g stays in comps.
