    In my original post, I did mention that I would be feeding both
constantly with 1:1 syrup into the fall, and monitoring overwinter.
 
I was not clear in stating that the new hive would be requeened with a
purchased queen.  I was not going to allow them to 'raise their own'
 
 What interests me is your comment relating to open eggs, larvae and
requeening.  Everything I read before posting my question was to leave the
original queen with mostly capped brood, and the split to be requeened with
mostly eggs and open larvae.  This was to minimize the impact on brood
cycles of both parts of the split.  The reasoning being that the
established queen would resume laying - providing new eggs.  In the portion
of the split recieving the new queen, mostly eggs and larvae were needed
because it would be 2-5 days before she was released and started laying
eggs.  In both cases, a break in the brood cycle of  a maximum few days.
 
  Switching it around could cause a gap in the brood cycle of 10 days (
15,000 + bees) or more in the requeened portion of the hive?
 
Any other feedback/experiences on capped brood or open eggs and larvae for
re-queening?
