fellas, just because addame has one queen cup in a hive does not equate to supercedure. if there were royal jelly in it with developing larvae and the bees were elongating the cell, than yes, or a number of cups.
if the cup is empty, i would leave it alone and keep an eye on what is going on.
"Supersedure queens are said by some to be inferior.. Maybe. Worse than emergency queens? No. Worse than swarm queens? Yes."
swarm queens are the best, they are usually very well fed, then supercedure, last emergency queens. if one opens a fully developed swarm cell, you will find that these are literally swimming in royal jelly, compare it to opening a supercedure cell or an emergency cell. lots of variables when the bees raise their own queens, time of year, flow, the health of a colony, etc.....a good queen is a well fed queen.
