I had an empty hive with foundation frames in my backyard and some bees moved in. It's been a couple of weeks now and when I opened it to check if there was a colony being established I only saw a few bees building comb on the side of the box, inside, and a few building comb on one of the frames. I didn't see any signs of a queen, no eggs, nothing. All I saw was some pollen and honey. Does anyone know what's going on? Why is there no queen present? I cleaned up the comb on the side of the box, removed the extra frames they were not even touching and closed it back up. Any advise would be helpful. Thanks.
