I dont know how long they were queenless but if no new brood for very long you will be short on winter bees. Existing foragers are close to their expiry date. Feed in hive and put insulation around and above the 2:1 syrup to keep them taking it as long as possible. Be prepared to add loose sugar on newspaper on frame tops. Consider some pollen sub if they are not bringing in lots yet. You need young bees as well as stores.Did a hive inspection today. Both hives are finally Queen right with great population. But they have no honey stores at all. None. What is going on? What should I do with fall/winter approaching?
