I followed Mr. Bush's link and found the following statement higher on the page..."Many beginners couldn't find a queen if you marked, her, clipped her and put her on one frame for them to find her, and even an experienced beekeeper in a well populated hive on a given day may have trouble finding one."
Personally, I don't think I could find the queen if you dipped her in red paint and tied a miniature bouquet of balloons to one of her legs.

Ya'll have a great weekend.
I can't wait to see what happens in Tillie's hive with the outed queen.
