How long does it take the girls to make a supercedure cell and hatch it. One of my hives went queenless and I found a cell that looks like it may have been a hatched supercedure. I am talking shortest case scenario. I went in 9 days ago and there were eggs, larvae and capped brood. Today there were no eggs and only capped brood. Is it possible they used one of the larvae, capped it, and hatched it in 9 days? I currently plan on waiting to see if a mated queen comes back, but I would rather not wait too long if this isn't possible.
