I took a quick peak under the crown board on Tina's box in the allotment to find Tina wandering around on top of the brood frames. So something is not right there. The last time I looked in there she was on the frame of brood I had added leaving the small patch of eggs she had laid un-attended.
I have taken the queen in a nuc from Box 6 (GW's old box) and taken them to Old Costessy. The queen came from Luke's (darker) Essex bees that were united with half of GW's bees and after the colony in WBC hive were the strongest colony on the allotment last week.
I've sited two new hives from Bill's apiary in the countryside on the allotment.
