I inspected this AM and I also saw drone brood in one of three hives I looked at. Not much drone brood compared to worker brood, but kinda surprised to see the drone brood.
My area is having a bit of a flow, lots of pollen coming in, hives gaining weight, maybe reason for some drone brood...??? Maybe.
I will add, one hive I inspected this AM had the one of the prettiest frames of bee bread and capped honey I have laid eyes on. Ready for winter.
