Updated, yesterday after splitting #3 queen was put in #4 bottom box with blue painters tape. The original #3 was full of bees (top to bottom) queen was in bottom ten of #3, moved her over to bottom #4 to do split , there was no Q cells drawn in original #3. Thats when we noticed #1 box covered and hanging. 12" below landing, I seen a Q in cluster, we brushed bees in 5 frame nuc. Cause we didn't understand were she came from. We left 5 frame nuc in front with a tele.cover. buddy went back today to introduce caged Q we got from CBT yesterday afternoon in #3, i wasn't there today. He said 5 frame nuc was empty. He intro. caged Q in #3. Said he moved nuc box out of the way, he moved lifted tele.cover on #1 and they swarmed out hole in inner cover and they lit up on a plumb tree 8' off the ground. He was able to shake in a box and all bees went in box after Q. He don't know how to sent pics. so i'll have some tomorrow.
