Have 6 hives, all about the same strength. All have the same configuration of 2 deeps with 8 frames and a honey super on top. All entrances on bottom are still on smallest opening. I have upper entrances on 3 of my more busy hives. Hive 1 has had bees all over the sides of it each day for just more than a week. I have checked and not found any queen cells.
After a hard freeze we lost most of our early nectar and pollen production. It's starting to pick back up again. I just don't know why hive 1 is getting covered with bees each day. I thought about opening the entrance reducer a bit more today. Any other suggestions?
