I had two very strong hives that swarmed and we captured the two largest swarms I've ever seen within fifteen minutes of each other 14 days ago. We had just recently robbed last Fall's honey and had wet honey supers so we thought they would be perfect to use for most of the swarm hive box frames. After seven days we did a quick check through all four hives and found a queen in one of the swarm hives but no eggs or brood on any frames in any box in any of the four hives. There continues to be a lot of activity at each hive but no noticeable pollen coming in and the boxes were full of bees & uncapped nectar/honey. I went back through the swarm hives today (14 days) - loads of nectar, some capped honey around the edges of some frames, what looks like a few pollen cells here and there, plenty of drawn out wax but still no eggs or brood. I've spent the last hour & a half perusing the internet and found what seems to be a multitude of answers but no clear consensus- how long do I have before I need to start worrying about being queenless? Should I go out and buy 1, 2, 3 or 4 queens? With all four hives without eggs I have no frames of brood/eggs to share. Thoughts?
