I’m a new beekeeper - started with a nuc around mid July. The nuc came on British Standard National frames, which I then converted to Langstroth frames to fit my flow hive. Problem is, after several weeks they haven’t filled out the gaps on the frames as a result of the conversion, which bothers me. In addition, few of the frames seem pretty old as well and I am thinking about swapping out all the frames for Langstroth frames, as I have a second box spare, and Langstroth frames with foundation.
A few questions if you wouldn’t mind:
Is it too late in the season to swap them out now? Wait till next year to do so?
If it isn’t, what is the preferred method to swap out all the frames?
