This is the hive which I started late summer. They only were on a few frames, I was concerned about their food, so gave them some sugar water before winter. Then it looked they were basically empty so added an empty box to put dry sugar on top of the frames through the winter. Mid April, they still had empty space in the bottom, noticed not the best brood pattern. I thought about taking the top box off, but worried that would upset their "plans"? So I added empty frames to it. (Foundationless) By first of May, noticed nice brood pattern, still space in the bottom, and not started in the top. A week later, 8 frames of the bottom 8 frame box had brood. Moved one frame up to the still empty top box. Middle of May they had 2 additional frames going with brood in the top box. That's when I noticed a queen cup. Which looked like it had an egg in it.
Now I've heard they start them and tear them down. But would they tear down one with an egg in it? Then I checked again Sunday, and the cup is now a cell. I checked through the bottom and found several queen cells, mostly along the bottom area, some in the middle. None were capped, but one was narrowing towards the end. I looked through and could not find the queen. I did see eggs in the top box and checked it again for the queen, but no luck. So many bees, hard to see the comb. And it was getting late. I didn't know what to do, so closed it back up, but worried I was going to lose half or more of my bees. Then I started thinking, if I just moved half to a new box, I would only lose a quarter of the bees. Why, if I moved them into three boxes, then I'd only lose 1/6 of my bees. Am I thinking right? So early Monday, I split the 12 frames up into 3 boxes. More than one cell in each. Still didn't see the queen, but there were still eggs. So many bees!
Questions:
Why did they create queen cells with plenty of, at least upper space, throughout most of the winter?
What will happen, assuming the queen is still there somewhere, when one of the 4 frame box's queen cells hatch out with the queen in it? Will they take half the 4 frames of bees and leave? Or could the queen kill the queen cell before it hatches? How often should I keep looking through trying to find the queen?
With my other 1 box hive, I had added an empty box of empty frames to it. I noticed their bottom box is full now, so I moved one frame of brood up to the top box. Is this what you have to do, to suggest they can use the top box when there's just empty frames up there?
(The more I do bees, the more it seems like an art rather than a science!)
