I don't get it. I am finding capped queen cells in almost all of my hives. Most have have plenty of room, if you include foundation.
Here is my theory,
It has been a stupid winter here, It would warm up for a week or two so then we would get cold weather for several days. What it looks like to me is that it has not been warm enough for the bees to want to pull comb, but warm enough spells for the queen to lay. Looks like she has laid everything that is available to lay in and now they are out of room. Now it's warm enough and the flow is starting so the queen is ready to lay full speed and has nowhere to lay.
Ive tried putting the foundation between drawn frames, splitting brood between upper and lower deeps.
This is frustrating, I can't just split every hive that has capped queen cells. Will never have Honey.
