Frank, Unfortunately, Coleen did NOT describe How she made the split, so I have no idea of the proportion of FORAGER AGE and NURSE AGE bees. She only said she made a split of "bees and CAPPED brood" If she had said, "OPEN brood and covering bees" that would have been a different "horse". It is a shame that beekeepers don't understand the importance of details like this one. Then, we would ALL be BETTER beekeepers than we are. Hope I have helped. George Imirie
