you can also use the stronger hive to assist the weaker one, and reduce swarm potential in strong hive at same time. They both would be superior honey producers as well. First you have to decide what your goals are for season. Increase hive numbers, or honey(comb or extracted), pollination, queens etc. This will help you decide what "path" to head down. From there, choose one of the many methods you read about or get from here. My first year goals were to have them survive winter. Second year, honey and expand by two hives. This fall, survive and now I want to avoid swarms and increase honey production. I only want one more hive b/c expansion is expensive and I may be out of forage in my yard soon. Therefore I will use splits to avoid swarms and recombine in fall for wintering and eliminating weaker queens to keep my numbers down. Thats the goal, I'll see how it works out!
