This is the first time I am experimenting with queen excluders. If anyone has experience with excluders could you advise me regarding the following:
The approximate amount time for bees to move up from a single deep brood box after it has ±8 or more covered frames. I am using all frames in both the top shallow honey super and the lower brood that have last years comb. I also placed an Emrie shim (second small entrance) above the queen excluder.
