Thanks for the advice all.
No worries here with Varroa, so not worried about that, and the honey is coming in faster than I can provide gear to the bees so not worried about that either.
Was just wondering if there was a quicker way to do it so the new hive created doesn't start from such a poor position.
Recently I spoke to a beekeeper who recommended splitting nucs to increase numbers. Get 2 or 3 nucs say, and when they are packed to bursting, split them into 2 and 3 frames to double your nuc numbers, and so on. That way the full sized hives can produce honey and the nucs can be there 'propogating' hive numbers
