I see the difference in your setup and I think I know why. You need to minimize your time-effort. so by sacrificing whole colonies everything can be more tight and organized than if you make nucs and queens out of the running apiary. I was as yet to samll for that. I am thinking of similar ways, if not the same. matter of ways to drive and matter of material.
_______
**Sacrificing one large colony will yield between 3 and 6 new colonies. You need to -invest- a colony to make more colonies. How many more depends on how heavily you invest. Take down a big hive, big investment, big yield. Take down a straggler weak hive, small investment, small yield. If no sacrifices are made, and resources are drawn from the main running apiary, then the whole apiary will suffer some, negative yield. Best to set the goal and take whole hives to meet the goal. As you say - for well organized streamlined work, as well as to minimize the impact to the rest of the apiary.
When a full double deep hive is taken down, it gives 20 frames of comb with bees and resources. This usually gives 4 to 5 new nucs. 4 nucs (2F) get ripe cells, the 5th nuc may be a bit larger (3F to 5F) is the donor queen, some bees, and a small amount of capped brood from the original hive. Any frames left over are used towards getting the divided 10F boxes prepared for later.
_______
I am thinking of putting 3 brood combs (I will sacrifice a few stragglers and the combs from swarm control) into a 5-frame nuc box with a cell. That will fill the box rapidly. when first hatch is emerging I migth add another 5 combs on top and/or do the thing with 3 nucs and 2 honey-supers.
_______
**A great plan. Just keep in mind that the larger the size of the nucs are made, the fewer number of startups can be made. Rapid expansion is focused on quantity of new startups. The mass/size building comes after the startup quantity goal is made.
_______
To clarify, some questions: You use "shook swarms" - only bees, no brood - in your (mating) nucs of 2 frame?
You do not use brood in there, but take brood for swarm control, give a cell and sell that unit off right away (after queen laying I presume)?
_______
** Correct. Most of the 2F nucs will have no brood at all when they are made. 1 frame of resources, 1 frame mostly empty but fully drawn comb. Few bees are used to make the nuc so try not to have brood for them to stress over taking care of. I want the bees looking after the queen cell and the new queen first and foremost. Yes, some small brood may be used in making the 2 frame nucs, however not much and is not intentional. When the hive is sacrificed, it will have some brood. Very small patches of brood may be put into the 2F nucs simply because they will also have some resources on them. The negative side of no brood is if the cell fails or the mating flight is lost, there is no retry with another cell. The bees will be too old. The nuc is shook out in front of another nuc or hive. Extra nucs are made to account for these. If the goal is 10 new hives, then start 14 nucs at the outset. Later when the results are in, losses tallied, the extra queens are sold and the nucs resources are recombined to increase the new colony mass/size OR the whole extra nuc is sold.
The queen cell is RIPE, meaning she is out within 12-36 hours. There is no delay between making the nuc and putting the cell in. When cells are ready, nucs are made that day and cells put in immediately.
Large patches of brood from the donor hive are put into a nearby production hive that needs a boost or has the bees and space needed to look after the extra brood.
You are correct on swarm control. When brood is taken (splits) for swarm control it is put into nucs and sold with a laying queen. I do not put a QC in with a lot of brood, as I view that like a supercedure/requeening situation. It is ideal if the timing of the swarm control for the main big hives coincides with the time to transfer the new and growing 2F colonies into the divided 10F boxes. When those stars align, swarm control brood is used to boost the 2F colonies as they are being moved into the 5F spaces.
Hope that helps!
