I recently tried a technique I read about in Bee Culture. I basically double queened a hive in order to get more bees into a hive body that had an insufficient amount of workers. After quite a time passed I moved the weak hive to my parents house to avoid having the workers drift back to their original hive. They have been up there for about a week so far but I want them back here because I have to fill their feeders and also I get a lot more sunshine here which stimulates their activity.
How long should I wait until I bring them home?
