Decision To Split Hive

One of my orchard hives has tremendous spring numbers and I didn't really have time to look at it fully until today. Temperature was 65 degrees with a light breeze. Lots of capped brood and an inordinate number of drone chambers. A sure sign of possible swarming hints as well as queen  possibility of going bad.  So with that being said I placed a queen excluder between bottom two brood boxes and placed another deep on top with mostly capped brood from below on top as well. I have two queens coming and will plan on moving the split soon.
