During the 4-5 inches of rain this morning, we were out looking at the flooding. My daughter found a small cluster on the ground under one of our 6 hives. I scoooped them up and put them back on the porch and found a new fresh queen (not marked). This hive had no Q-cells on Sep 27 as I did my fall check and downsizing. Saw none in the other hives last week either. So she may have come in to our yard which would mean a feral as no one else within 5 miles has bees!! What is the best method to keep her alive until next season? I know I have seen some info on keeping a queen in the top of a hive during the winter. Is that using a Q-excluder below her? Like a two Q hive?
