Hi all. I tried my first split recently, and I believe I did everything according to plans. It is now nearly three weeks later and I see no eggs, and because it is a really big hive I can't seem to find anything that looks like a young queen. The bees are agressive when I check the hive, so I am hoping that means there is a queen in there somewhere. When should I consider requeening (I have plenty of eggs in other hives I could put in to to force an emergency queen, or I could buy one. I even have a weak hive I could merge with this if need be, just to get a new queen in there. But if I introduce a new queen and there is a queen already in there on the verge of laying, does that risk losing a swarm? Timing is everything it seems, but I don't quite know what the timing should look like at this stage.
