Try2BeeGood. Colonies of bees will all build up differently. Some will raise more drone brood than others, that is a sign of nothing. Drones in a colony are a good thing, it means too that the colony is feeling good about themselves, hee, hee, that they are strong enough to make drones. All colonies need and make drones. The uniformity in the frames that you described as a mountain will probably work itself out eventually. Don't worry too much. It sounds like the colonies are building up just fine. Welcome to the world of the bees that keep us guessing all the time, wondering what on earth they are up to. Have that most beautiful and wonderful day, lovin' our life. Cindi
