On one of my hives I have a frame that is 100% drone comb, on a foundation less frame. It came from a nuc I bought last year. The queen continually lays drones in it, and that hive is typically overflowing with drones because of it.
Should I keep it in there and let them do their thing? The amount of drones in that hive is typically excessive, I was thinking of maybe freezing it every few months to help with mites and keep the drone numbers in check. The drones seem to all hang out in the top super, probably to hide from the workers who are trying to kick them out.
