Beekake ..... I like the off hive system of clearing bees.
At a convenient place in the apiary, I set up a stand. On the stand goes a knock-up floor which is open front and back. Above this goes a clearer board for the bees to go DOWN. Now comes 4 or 5 supers of honey and bees. Topping this is another clearer board for the bees to go UP. Finally a reversed double exit floor. This stack is left for 24 hours then the supers taken away for extracting.
With this system you can have supers in the stack from different hives without a problem. It also means that you only have to disturb the production hive once.
If the weathers bad do they still fly back to their original hives?
With different colonies honey supers and bees stacked together is their any robbing going on before they fly back home?
