Beekeeping: A Feeder / Donor Hive.
I'm showing the advantages of owning a feeder hive. Taking a frame of brood from a large colony of bees can be quite daunting. It's so much easier to remove a frame of bees from a dedicated feeder hive. A feeder hive is also useful for beginner beekeepers to become familiar with finding the queen & learning how to read the brood.
