I'm happy to say that my transfer of Colony 11 from its nucleus box to Hive C have been successful. There is pollen on the hive floor; debris from cleaning of the framed comb and evidence of new comb building. There was also lots of activity at the hive entrance.
The less welcome news is that the comb building is happening beneath the nuc' box lid. I had hoped that they would move onto the framed comb and leave the lid area alone. That hasn't happened so I'll have to do something a bit more destructive to sort the hive out so that it has only framed comb in it.
