I have a hive that was healthy but now is not producing much brood. Earlier in the season it might have swarmed but I never saw a drop in bee numbers. Last month when examining the hive I found no brood - zero. I added a frame from another hive that had brood and in a few weeks was getting brood, though not the best pattern. Today, about three weeks since last exam, very little brood, just a little spotty brood, most frames empty. So it looks like I'm headed back to having no brood. Thoughts or ideas about this would be appreciated.
