I did a trap-out on a bee tree about 7 weeks ago. We went and retrieved the box today and brought it home. When we got home I checked it and can't find any brood or eggs. I guess they didn't raise a queen from the eggs I originally put in there, or something happened on her mating flight. My question is do I have enough time to introduce a frame of eggs and let them raise a new queen, or do I need to order a queen. Or is it a lost cause and I should just combine them with an existing hive?
