Trying something new this year. End of June I pulled a few frames of brood and the queen and placed on top of colony on its own BB facing opposite direction. Notched the bottom colony OTS style. Today is day 14 , so went to check return on mating flights (ya a few days early). Got 3 unsure (saw the virgins/ queens though), and all the rest are mated. My question is; How long should I wait before adding news paper and excluder to make the 2 units into a 2 queen setup for fall build up? I'm worried if I do it too soon before the queens come into full lay that they could squeeze threw the excluder. Allot of the queens have only a silver dollar worth of eggs. Thoughts? Planning on pulling the old queens and over wintering them in 4 frame side by side nucs rather then pinching them as most are in there second year.
