When beekeeps refer to 4 frames of brood, do you mean 4 frames with brood on both sides, or does a frame of brood refer to one side of a frame having brood on it.
Not a big deal but occasionally you read about performing a certain function when you have X number of frames of brood, or someone bought a nuc with 3 frames of brood, or someone will describe a hive inspection where they saw X number of frames of brood and I was just wondering if that meant there were brood on one or both sides of the frame.
