"he advocates making strong five frame nucs and leaving them to raise their own cells. I suppose its a case of being ok if you know what you're doing and make sure there is plenty of young bees and nutrients to make the emergency cell, its not something I'd suggest to a beginner though."
presumably would be good idea to place the nuc where parent hive had been for 5-7 days to get a boiling over cell raiser.
Jay Smith said that bees cannot tear the old combs down in order to build a proper queen cell.
You can help them out by tearing out the bottom 2 ribs of the brood cells with your hive tool. This is the MDA Splitter on the spot queen rearing method. It works good if you only have a couple hives and you don't want to set up a cell starter and so forth. Of course, the colony raising the cells needs to be strong in bees and pollen. It works best when there is some kind of flow going on.
