That is interesting how they started from the bottom, I recently tried foundationless and they all started from the top and built a natural comb shape but none of them have connected them to the bottom. They seem to be finished as they filled them with capped brood and went to another frame. Kind of off the topic, but I also have noticed that with using every other frame drawn out they will draw out a small portion of the foundationless and cap mostly drone brood in this area. Seems that they prefer to put drone brood and supercedure cells in a frame that they have drawn out. Just curious, has anyone else that has went foundationless noticed this pattern?
