And then there's this:
I've always been of the opinion that the queen is usually in the top 1/3 of the swarm cluster. But there are exceptions, as I've found after swarms with the queen near the bottom.
On the other hand There is a place within a hive that you'll most likely find the queen. I usually find the queen on frames 2,3 or 4 or 6,7. or 8 of the brood chamber in a 10 frame hive. If not in the top brood box then in the lower. I've been beekeeping for 50 years and with few exceptions I've found the queen on one of those frames. Speeds up locating the queen dramatically, why look on every frame if you don't have to. If i'm going into a hive with the intent to find the queen I look first on frame 4 of the upper brood box, then frame 3, then 2. On the opposite side I look at frame 6, then 7, then 8. If I don't find in the upper brood box I go to the lower one. The most frames I've ever had to pull, when purposely searching for the queen is 10 on a double decked brood box.
With Mediums, and the brood box extending into 3 and even 4 brood boxes (8 frame), the procedure is the same. I can still find a queen faster than anyone I know and I've been doing it since I was 10 years old. List that under things my mentor taught me.
