IToday was a high of 74 degrees and we first looked at the hive at 5:30 pm and there were several hundred just hanging out
74 is not hot . 90 is hot because it is same temperature as in brood area.
You should inspect your hive.
* Look old brood how much is going to emerge brood.
* one full brood frame broduces 3 frames of bees.
* look how much bees have empty combs where to put pollen and honey
* look how much you have ventilators on entrance
Normally in spring they burst out because they need more room.
YOu may put one Langstroth down and medium up. Take exluder away.
When you add supers or deeps you may give 3 langstroth boxes first and no exluder. Bees can make so much brood as they need. After that give mediums on so the topmost is full of bees.
Add always empty super between brood area and honey. Then turn second and third box in two weeks cycle.
I use that and I need not excluder. In late summer you may use excluder when you take all yiled away.
