My bees have swarmed three weeks in a row. This is my 2nd yr of beekeeping and I had just one 2-deep hive. After the first swarm, I removed one of the old deeps and added two new deep hives. Is it that the bees do not like new hives and new frames? They seem to just hang around the entry; there is not a lot of going in and out of the hive. Are they too hot? The weather has been 70's in the day and 40's to 50's at night. Is this too much of a swing in temperature so they get too hot in the day? After the second swarm, I left two queen cells. Today, after the third swarm, I left only one queen cell. How do the bees behave when they are waiting for the queen? Are they still supposed to be in and out of the hive foraging? And how do I make more ventilation? Should I make a space between the deeps or below the super?
