I am in NC. I have 3 hives. I inherited 40 mediums full of drawn comb as well as 6 deeps. I want to do walk away splits with With my 3 hives and end up with 6. How far into spring before I have enough drones out there for the queen to mate? Will I know it is time when I have queen cells in my hives? I pull those and move them along with some bees to the new hive?
