The Calm Before the Swarm?
With this hive, you notice there are four boxes, with a queen excluder. I did put a honey super on 3 weeks ago, and when I checked last week there had been a little comb drawn out but not a significant amount. I think there is enough room in the hive, though this queen seems pretty vigorous. Maple, ash and birch are producing pollen at present, and the dandelion bloom is in full stride. There may be an early honey flow if the promised warmth of the coming week holds up.
I also added a super to hive #1, though the new frames I had put in the top box were only about half way full. With so much in bloom right now, I want to stay ahead of the game.
