Not really following your question, but I think Danno has the right answer. I know if you take cell cups from the Nicot system with eggs and invert them in a cell bar without waiting for the larvae to hatch, the bees will clean them all out.
There's the answer that I was looking for. I just thought the bees would wait for the eggs to hatch and then use them when they were ready. I didn't know they would clean them out. Thanks for the info.
