I have read previous posting on requeening hives without looking for
the queen.
I raise my own queens.  When the queen in the mating nuc shows
good laying pattern, what would happen if I just took that matting nuc,
removed the bottom, and placed it ontop of a torn sheet of newspaper
on an inner cover hole on the hive that I want requeened.  Hold the
mating nuc down somehow and leave for a week  and let the two units
merge.  If about 90% of the time the younger queen will dominate,
then alot more work is avoided when requeening my hives.  Right??
And the 10% of the hives that keep their old queen are probably better
off with thier old queen.  I do not want to requeen my hive with a
weeker queen than what was in there to begin with.  Can someone
comment on this and point out any problems that I am not aware of or
maby overlooking.
