Where are the eggs???

Today I refilled the inhive feeder and entrance feeder. The bees are calm. Weather will be getting colder again. I am seeing NO EGGS OR BROOD, but pollen and sugar syrup is evident in some cells. The past few days it was finally warm enough for the bees to actively fly. But why are there NO EGGS??? Maybe it's the weather. I suppose I'll wait till the next inspection before I take action. The Beeline was noted and I observed a 3pm rush hour. It looks like a thin cloud of bees hovering in front of the hive. I am happy to see the bees doing their thing.
