Re: Options for hive combine
Not a good plan to combine because as long as the aggressive one might have a virgin you have a very high risk of losing the less aggressive one.
And the aggressive hive will also kill any bought queen you introduce, if they have a virgin.
Best plan for now is wait and see if a laying queen appears in the aggressive hive over the next 2 or 3 weeks, most likely one will. Meantime if you wish, you could put a comb of eggs from the less aggressive hive into the aggressive hive, and wether or not they build queen cells from those eggs will tell you if they have a queen or not.
