I checked a hive that came from a split today and I found two queens in it.
There are newly fresh laid eggs so the older queen is still in there.
A new queen that hatched from the queen swarm cells was on the same frame, but on the other side.
How long before the workers eliminate or they eliminate each other ?
Could the hive possibly have both queens for an extended period of time ?
(I've heard about this case in supercedure procedure where the old queen is still around for a bit).
