I opened my hive today and in the top box I found nice capped comb, filled with honey. I didn't find any brood in the frames. We are just starting in on our second year keeping bees, so I still feel like I don't know what I am doing. I have two deep boxes and one smaller one on top and there was no excluder. I took the top box off to check the lower boxes, but the bees were getting agitated (and I was getting nervous!), so I am not sure if there was brood down there or not. Does it sound like I have lost my queen? If I have, what are the odds that the hive will make their own queen?
