I did a 'hard' Demaree on Saturday to help me find the queen I have never seen.
The previous week the colony had been on two full brood boxes and 5 supers, with no queencells. At the weekend queencells were evident so I put a queen excluder on the floor and an empty brood box plus just one drawn comb and two of foundation. I then shook all the bees from the two brood boxes into this brood box, then put the queen excluder on top, the supers, another queen excluder, and then the two BB's - minus queencells. Two days later I took the hive down to the lower brood box and there was the queen on her one frame as I had hoped - with no eggs so she was ready to leave. She is now marked a fetching pink and clipped as well. In the top brood boxes, I removed all queencells again and put in some grafts as the colony is suitable for queen-rearing. The next job is to check the progress of the new grafted queencells, re-check for unwanted queencells and clear two of the supers over the top brood boxes.
May your bees read the same books as you do.
