After seeing the fanning at the purple hive last night I think the town swarm queen may have ended up in that hive somehow and was accepted since the hive just swarmed and was raising a queen. I looked in both today and there's significantly more bees and the orange hive is empty. I'll check my swarm traps tomorrow just in case but I believe they migrated. I've only read about something like this a few times but never seen it happen. I'll see what's going on in the hive for sure this weekend.
