Ok this has started to bother me a little as with all the information I've read it seems a bit odd. I have yet to see a drone cell in any of my hives. Both hives look like they're on the verge of a population explosion and needing another medium brood chamber; since the hives have started expanding and all but the top portion of and a few little spots here and there are packed with worker brood going on the 5th week since installation. Does this seem a little odd to anyone else or am I just being a worry wort? Oh and there are a few drones here and there, but they either came with the package or came from another hive as I'm positive I've not seen a capped drone cell.
Have you put a smaller frame inside the brood (super frame) so that they can make drone comb on that?
