I have 14 nuc's and they are 12 days on since the queen hatched, and there is no sign of laying but the weather has been poor for the last week so I am assuming it is because of that. How long will the bees tolerate an un-mated queen/will they kill her. And is there a time limit for her to mate?
12 days on since the queen hatched,
subtract... Poor weather, 7 days
when the queen was 5 days old and ready for mating, the weather turned bad so she's waiting for clear skies. Hopefully you get a few days clear and warm soon, she'll be needing to mate within a week from now. Any later and she may not turn out so good. I think it's more weather related, yes.
