Went back last evening to split the big hive. They still had 1 lb of bees hanging on the cover. I opened them up and they had filled 3 frames in the super I had added last Friday eve. They are now in 2 separate hives. Hoping to get them where they won't cluster on the outside so I can load them up to move. Former owner says, "no hurry, just want them moved". These are pissy bees.
BTW, I never found the queen, but was hard to look with so many air-borne bees!!!!!
