I have one hive that is very strong... 2 brood boxes + a medium. Then I have a weak hive that appears to have lost its queen as there is very sporadic brood? I am getting a new queen for them on Thursday and would also like to give them a frame of brood from the strong hive. How do you remove the bees from the frame of brood after removing it from the brood box? Shake the bees off and brush off the remainder back into the brood box??
