What is your equipment like? Colonies in two deeps?
If yes, equalize brood in both boxes, take one away to another yd and install a cell in each half. Don't look for the queen. Your time is worth more than a cell. Check them all in a week and the boxes w/ eggs have queens.
You can do that into nuc boxes too. Take a hive apart and put what you want into your nuc boxes and install a queen cell in all the parts.
