I run three deeps(10 frames) from early spring until the spring flow is over, about late June early July. Then I will harvest the honey as soon as possible(before the queen slow down for the summer dearth), then if I need more hives I will immediately split the strong hives(usually they are very strong) by taking a deep and put it on top of another empty deep on a bottom board. I can do a walk-away split, buy a queen, have a queen cell in the split or hope I have a queen cell in one of my other hives. I let the fall honey flow for winter and feed if necessary. Winter over with two deeps.
