We've had a streak of warm sunny weather (low 70's), so I opened the hives today. One hive is really weak, essentially a grapefruit-sized cluster actually sitting on brood (1/3 of a frame on both sides).
The other hive is booming - 2 full frames of brood, tons of bees.
If I swap locations in the middle of another sunny day, I could pump up the numbers of the weak hive, right? What if the sunny day is followed by days of rain - any chance they will reject the new bees?
Anything else I can do? They both have plenty of honey stores. . . .
