The nurse bees on the frame always go with the brood. I've never seen any problems. Obviously, you must make sure that the queen from the donor colony is not on the frame that you take. I always assumed that a weak colony would need the extra bees anyway, to help take care of the additional brood but as always, I yield to the more experienced folks out thar!
Yes but.... If you leave bees on the frame, thay can attach on new queen. At autumn this is usual.
When you put bees into another hive, they return to their original hive. Some come later and if they have foreign odor, they will be killed.
I cannot see advantace enough to move bees with frame. Only few will stay in new hive. I have done this 40 years. If hive is weak, foreign bees attach easily on queen.
Every late summer I join 2 frame nucs to one box hives, and if I am not carefull, they kill the queen with 90% insuarance. In the middle of summer things are otherwise.
