I pulled some mated queens from my nucs this morning and would now like to combine the queenless nucs in order to free up some of my equipment. If I wait 24 hours, could I just stack the queenless nucs on top of eachother without the newspaper combine or will fighting occur? I would like to keep two nucs going and allow them to make another queen so I don't want to combine them with my queen right production hives at this time. Wondering if using newspaper in this situation is even necessary.
