I'm slowly/informally regressing 2 of my hives to natural comb, using standard deep Lang frames (Pierco), from which I basically cut out the entire middle, leaving only a strip around the edges. I've been occasionally swapping out regular frames for these modified ones all season. Seems to be going well - especially if I put a new (modified) frame between 2 existing ones... they'll build it up with comb very quickly. Very cool, and these hives seem very happy.
I saw something last night I wasn't expecting though. One of these hives is 2 deeps... probably about 8 frames have been modified and these sit amongst the remaining regular frames. What I noticed was that most of the brood on the modified frames was drone brood! I have not noticed this before. The regular frames were just about all worker brood, but the modified ones were almost all drones. Anybody seen this before?
Thanks!
