Swarming behavior with no swarming?

Definitely a winter split in these parts! Not the norm for sure. I decided to go for it because the colony was so full and was making drones, as was the other overwintered one I posted about even earlier:

It was a gamble, but I figured there might be other drones around if I had them. I insulated and fed it through another cold spell. Temps are dropping after today but nothing below 45 at night/upper 50s during the day and there’s plenty of forage now - it’s going well!
