... I intend to move them to a poly national the first warm day in spring...
Today was the day - 18C and no breeze, so I took the opportunity to move the bees into a poly. It went very well, I took off the lifts, moved the BB a couple of yards away and put the poly in its place, then transferred the frames one at a time. Considering the hive had no attention for two or three months prior to me buying it in November the comb was very orderly, no brace comb and just one frame I had to discard because it had only one lug. Fortunately it was an end frame and was so well propolised I had a job to move it which I guess is why it stayed in place while only supported on one side.
There are plenty of bees, nice and calm, BIAS, and, joy of joys I spotted the queen, walking calmly about. I was able to catch and mark her so I can find her again
(White as I have no idea of her age - the seller was vague and unsure when I asked)
The bees were not the least phased that their home had changed shape and colour and within 15 minutes of me putting on the roof all the flyers and bees left on the WBC floor had made their way inside.
So I'm very happy today.
When I find the strength I'll lug the WBC home and put it in a sale - the lifts are SO heavy compared to handling a poly.
