Re: split question
i agree with your point about keeping nucs to draw resources from to boost or requeen other hives.
i disagree with letting a nuc raise it's own queen though, especially after the main flow is over. i tried that a few times and the emergency queens the little nucs came up with were not as good on average and tended to fail more.
that's one of the things i like about the cut down split. the strong parent colony makes the new queen instead of a weak split. doing it just prior to swarm season and main flow has the other advantages as well.
since the op only has one hive, i think he has less risk by waiting until spring. having said that, i just finished making up 15 nucs for overwintering, but i used mated queens from caught swarms and some grafted ones raised in a strong cell builder.
