I’m worried about my bees. They have been chewing down the flow frames, not like previous pictures from other people which show cracks etc. but properly chewed down. This makes the surface of the flow frame wavier in gradient, much like natural honey comb can be. I’ve attached a (not very good quality) picture.
There are two brood boxes with one flow box on top. Last inspection a month and a half ago, they were cleaning honey out of flow frames, and honey bound in the brood boxes (I switched some of the brood frames out with clean frames). Now, the top box is completely empty. I’m not sure what to do… I don’t personally inspect the hives, the primary carer of the bees is on holidays until the end of January. There is a heatwave in Sydney at the moment, and I am concerned that perhaps they are reacting to a dearth. I fed them sugar syrup today. My other flow hive (1 brood box + flow frame box) are doing fantastically, I harvested a frame from them today. They are in the same backyard.
Any thoughts? Advice?
