I moved a frame of eggs and brood into a nuc on 7/22 and they were capped by 7/29. I'm trying to estimate hatch date, but I'm not sure how long it takes them to cap a cell. Is it a days-long process, or can they whip one out in a few hours? The kids want to sit out and try to see the mating flights, so I'd love help trying to figure out a reasonable window.
