Can I leave them on with the queen excluder in place? Or will this be a problem for the cluster as they move up?
Take out that excluder so your bees can move the stores
were they want them. They'll do what's needed so they
can survive the winter. Don't woory about brood in
the supers, as long as they get through the winter and spring.
Better live bees with brood in supers vs. starved dead ones.
