Re: How early can you transfer queen cells to Mating Nucs?
Bees will have fully capped cells about 5 days after grafting. It is possible to do it that early but I would advise against it. Cells are best handled as little as necessary before day 10 after grafting (5 days after being fully capped) At this time they are around 24 to 48 hours from hatching. At this stage the cell has a tough fibrous cover and the royal jelly should be fully consumed. Any cells that still have rj at this stage are probably not healthy and any cells that are "open" would be a result of the bees recognition of this and they have simply cleaned it out. Best of luck
