I split 2 of my overwintered hives on May 11. I made one 10 frame and 2 nucs. Today I checked for queen cells. The 10 frame had several, the nucs none. I swapped a couple frames of bees, brood and queen cells to the nucs. This still left a few queen cells in the 10 frame. I figure those queens should hatch around 5/26. How many weeks after should I check for brood. I figure a couple at least. Please advise.
