Is it a problem to have really unbalanced hives next to each other? One hive is 3 boxes full, just added a fourth. The other hive is working on filling their first box - I have been giving them frames of brood and I'm feeding them. They were really weak coming out of winter, but they are coming back fast now.
Should I increase the brood transfer between them, or swap locations or can I just keep going the way they are?
