Checked in again last Sunday. All of the hives seemed to be doing well. I took 10 more frames of honey from the hives. I took the first frame of honey from hive #3 - this slow producer may finally be waking up.
On Friday there was a weird occurrence outside of Hive #4. There was a mini-swarm on the old fence sections that were laying next to the hive. There was only a hundred or so bees and I didn't see a queen. I went ahead and put them in a box with a couple of frames to see if they would either attract more bees (a queen was there) or not. After about an hour I went back and the box was empty - either they went back home or found another place to go. I may have to look more deeply into this hive to see what is going on.
