The bee inspector thought I had a Q- colony a couple of weeks ago. I had called him to check for disease as i was concerned.
I had never seen this queen since i was lucky enough to see her go on her mating flight so I did not totally lose hope but prepared to pension off the colony.
Last weekend I opened up to find more bees than before and saw queenie strutting around. I think they were stopping her laying as there were not enough to keep the brood warm on cold nights/mornings.
We have had some very cold nights and wet days here so even with fondant on they have had a hard time. Also this colony was in a shrubbery for protection against the wind but I believe this worked against them as it is so shaded and damp. They are now moved to a sunnier spot with a paving slab underneath, two breize blocks as before and timber supports under the floor. hopefully now they will have a better chance of increase. Both colonies still have their 4 inch cushion of insulation on. The other colony has been slow to build up this year and the queen stopped laying a couple of weeks ago. I believe the same was happening there as every second day has been cold windy and wet.
