How quickly can bees fill a medium super with drawn out frames. This is my second year and one hive in particular seems to be filling supers rather quickly. On Saturday I added a second super to this hive. In reviewing my notes I forgot to transfer a frame of eggs from this hive to the one that the queen has gone missing from so they could get a queen. So tonight I went looking for a frame of eggs in the process of looking for a frame of eggs I removed the two supers and both were basicly full ( one 10 of 10 full frames and the other 8 of 10). I added a third super to this hive. None of this honey has been capped so have to wait for it to be capped. So high can I stack supers? Should I add an additional top entrance somewhere in the middle of the supers?
