We did our hive inspection yesterday and could not find the queen, eggs, or young larvae. There were seven or eight queen cells embedded in the comb, probably emergency cells. Three or four were empty, and the others had larvae in them. We removed all that we found.
Several of the frames had capped brood around the edge of the frame, and the center of the frame looked like it was filled with liquid. Would this be nectar? Is this what back-filling looks like? Or could it be larvae swimming in royal jelly?
Will bees back-fill when no one is laying eggs? There is plenty of room in the medium super above the second deep.
