I am not contemplating this as I don't use top entrances, but I was just thinking about this today since I had a swarm depart last weekend from my backyard hive and figure the new queen is probably near doing her mating flights.
If you have a queen excluder and top entrance, do people ever run into the circumstance where, after a swarm, the newly mated virgin queen comes back through the top entrance and sets up shop in your supers?
Just a curiosity. I would think it would happen.
I am not bringing this up to debate the use of excluders - that isn't the point (I actually like them, although I know many don't, but again, not the point). Nor even the merits of top entrances. Just curious if this queen returning into the honey supers thing occurs. :?
