Re: very basic question
A queen breeder named Steve Tabor devised a special tool to move eggs into queen cells, but he found that the queens produced were no better than those made from larvae 18 to 24 hours old. The nurse bees removing and eating the eggs was a problem for him also.
If you time your egg hatch, and you put the frame of eggs in a queenless starter so that you will have eggs hatching 12 to 18 hours before grafting time, you will find larvae that the bees have selected at hatch to make into queens. Those will have 3 times the amount of food that the average brood cells will contain. These larvae will be the same as if they were grafted eggs.
