I caught a small swarm March 15th, so they have been in the hive about a month...they only cover about 3 frames, but they have been very active when temps warm up.... I looked in on them this last Saturday and they have comb and even put honey and pollen in it, but I see no brood or eggs anywhere....there is something that looks like a queen cell in the middle of a frame that has hatched already....but I didn't see a queen and I looked them over pretty good....what could be going on? there has to be a queen for them to be making comb and filling it with honey and pollen don't they? and why no brood or eggs after all this time? And how did they make a queen cell with no larva anywhere else, or could they have all hatched after something happened to the original queen, but there was an egg they made another queen from?
