I've got my "best" queen, from 2018, made honey then, lots of honey last year, biggest hive this year on track to make honey again. Ideal brood pattern. Gentle, I can push them around with my finger. Doing something right about mites.
But I can't seem to raise her daughters to queens. Grafts dont take or get torn down. "OTS"-style splits, they only raise one QC per frame, and then when I put them into nucs they don't come back.
Two rounds of failing to raise this Q's daughters failed last year and one so far this year. All the same methods, same time, same yard, different queen-mother, successful.
What gives? Have you had this before? Is it maybe some genetic predisposition against raising daughters?
