I have put excluders on the brood nest, then previous years drawn comb and waited till the combs were all being filled and took the excluder off. Go back in a week and the center frames have a big arch of eggs and larvae. The workers had to have emptied those cells for the queen to lay in. That is determination!
These bees I have sure dont follow the same rule book that makes claims that queens wont go up and lay up the supers. Maybe different bees, different flow patterns, cold nights, short season etc., make a difference, but some of the blanket statements made about excluders sure dont apply everywhere.
I dont want to have to work around brood in hone supers when I am extracting. I also dont want to play the game of separating frames or boxes and waiting for brood to emerge before extracting. I consider excluders a big plus for me.
