Re: Did I kill my Queen? NNOOOOO!
Unfortunately, a day does make a difference. It takes 3.5 days for a freshly laid egg to hatch. So by looking on day 3, there could still be unhatched eggs from a now deceased queen. However, if you saw a whole bunch of eggs, especially if they where standing up, it would be a sign the queen was alive and laying.
I had hastily made a nuc in a downpour on the19th. I was not sure where the queen was, so checked it on the 21st, two days later. There were still plenty of eggs in the donor frame and no queen cells started, thought for sure the queen was in the nuc by mistake. Four days later I had capped queen cells and all was good.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
