Is there a specific order-check boarding pattern-sandwiching when you add a second broods box on top of full bottom brood box that the frames are full in?? Then——-how to manipulate the bottom brood box with new frames amoungst the full(old) frames??
I generally take the outer two frames of the old box (usually honey frames) and put them in the centre of the new box separated by an empty frame. In the old box I put two new frames in the middle so the older frames work their way out.
This works well in the warmer seasons but varies significantly in cooler months if you have to intervene.
