I did a cutout earlier this month, and it had swarmed previously, so the hive was full of ripe queen cells, but no queen. I found the presumably mated queen last week, she was nice and fat, but she hadn't started laying yet; no sign of eggs or larvae. I cracked the lid today (I found the entrance reducer on the ground, wanted to make sure there weren't any unwelcome guests!), and looked under both deeps. Through it all, I didn't notice any change in hive temperament, sound, anything. However, these bees even during the cutout were the calmest bees I'd ever seen (not that I have a whole ton of experience), and I still say that, with 5 swarms captured and 5 packages added this year to my overwintered hives.
I wonder if the increasing temperature is more the cause of more bees hanging out on the landing board than the state of the queen in the hive? More bees will hang there as it gets warmer, for sure.
