I got to my bee yard area early this morning and was startled to see a good size swarm on the fence 5 yards from the nearest hive. I haven't found out where it would have come from my hives yet, and am 75% sure it didn't, unless I missed a hive in the last inspection. I looked in the couple under suspicion when I thought about which one it could have been.
I took a frame of brood from a colony real close and got them started into the box. I had to hold the box in place for 30 minutes while it rested on a barb wire strand and they marched into the box. Over 2/3 of them are in the box by now.
Notice the hive tool bridge to give more traffic lanes.
