"I agree with Iddee and riverbee. this queen is producing enough winter bees to take the colony through to spring. And Iddee could be right on the swarmy bees the early swarming could have been somewhat started and caused by beekeepers actions. And not have been totally bee genetics."
"Jen we are in a drought and the queen will slow down egg laying when no nectar coming in. Some queens just slow more than others."
jen, what apis said about producing winter bees, and what rod said. i hear ya, the queen has never ramped up. this is why it's good to have more than one hive to compare and educate ourselves on queens and bees. bees need both pollen and nectar. if either is absent, some queens as rod pointed out, will 'slow'. it's possible that this queen is of a genetic trait to be conservative. you said she was 'robust' 'laying well but not a lot'....it's possible that she is not the most prolific queen but maybe for dearth reasons, this is not a bad trait, given your dearth and as long as what apis said, "the queen is producing enough winter bees".....and she appears to be. i would not replace her (for me this time of year), and would evaluate her next spring.
