Late this afternoon, I put away the empty supers from extracting honey last week. I checked Hive#4 and they still had some space. Added super to Nuc #5 with 7 empty frames and 3 full frames of honey from Nuc #4.
Nuc #4 needed some space.
I'll probably do some more rearranging later next week. I need to check #6 for a queen. I could do some more extracting and take more honey - we'll see.
