Hi all. I split my heavily populated hive 2 weeks ago tomorrow. I was told to wait 3 weeks before going in to either one, since we didn't know where the queen was. Both had all the necessities. I added a box to the "daughter" (8-frame deep) right away and have been feeding that one. The parent is 3 boxes of 8-frame mediums. Had lots of brood. It seems to be quite crowded now. Should I add another box even though there is no nectar flow right now - which sounds like I would have to feed. Or should I wait till the fall flow and add it then? Will they still consider swarming? Side note, both boxes have acted quite "normal" even though one had to be queenless. Is two weeks too soon for them to be irritable, or does that probably mean the queenless one is just busy making a queen?
