I just checked one of my NUC splits I did about a month ago. It appears all the honey has been robbed out of it. Pretty sure it was robbing as I saw a ton of bees flying around it the other day, when I reduced the opening to only allow 1 bee in at a time. Haven't seen them massing around it for the last couple of days, guess they got the last of the goodies out about 2 days ago.
I'd like to save it as I saw the newly raised queen in there, no brood or eggs yet though. Thinking that's due to no food stores beeing available.
I've put a top feeder on to get them going and given them a frame of almost ready to emerge brood to help with their numbers. Question is, should I close off the entrance completely for a day or two, or keep it where it is and see how it goes? I'm only on an acre so can't really move it all that far. 5 other hives here. Any other advice?
