Brood in top box

[Johngerm]

Hi all

I have a problem with brood being above the queen excluder.  The excluder is in good condition, no bent bars.  It happened last year.  My queen is not marked so I put all of the bees out of the top box onto a sheet in front of the hive and it seemed to cure the problem but it has happened again this year.  How do I stop this happening again?

Thanks
John

My first question. Is there wet brook also below the excluder?
Your queen may have moved up during your last inspection.
Do you have a top entrance? Your gueen may have walked out the front door and into the top entrance. A good very experienced beek friend documented it happening to her.
Look at the brood in both areas. Look for eggs, if you find them, the queen has been on that frame within the last 3 days. Is there wet brood, if so, the queen has been on that frame for 3 to 9 days. If the brood is capped, she was on that frame, within the last 10 to 21 days.
If you have eggs in both the top and bottom boxs, you probably have 2 queens, mother daughter laying.
If the brood turns out to be drones, you have laying workers above the excluder.

Two queens is more common then we think.
