I've been feeding frames into one of my hives to get "natural" comb. The comb looks really nice, but a lot of it is really large cell.
Some of this really large cell comb is now filled with capped brood. If this were on foundation, I would say it's worker brood. The cappings are flush with the comb. But I find it hard to believe that these are workers in such large cells. Will drones have bullet shaped cappings in these large cells or could these be drones with flat cappings?
I should have moved these frames over to the side of the hive a little more quickly and maybe they would have filled them with nectar, but you know how schedules are.
