when you transferred the eggs, are you sure you didn't take the queen with them, by accident?
out of curiosity, when you transferred the larva, did you mush the cells of young larva to get them to make queen cells, or were you just hoping they would as is? I think they pretty much like to pick their queens at around 2 days old myself, and I'll often crush the bottom of the larva cell at a 45 degree angle away from the 2 day larva, as close to above them without touching them as I can, and they'll make them queen cells. I know quite a few others who do this, in fact, I learned it from someone who does this, and has for decades myself.
