Steve, can't answer all your questions, but I agree with Kirk, I don't think that you need to feed the pollen patty yet. If the hive is heavy, they would surely still have enough pollen and honey. Let them be for now.
I'm wondering maybe you didn't see any more bees flying is because they had taken a cleansing flight and now they were taking care of things in hive instead. There is nothing to gain from nature yet for the bees, too cold. Not sure, but that may be a thought.
Last year when I took "revive the hive" with Ron, it was March 4. That same day I gave the hives pollen patty. When I was in the hive that day, I saw lots of larvae, no capped brood yet. So, if you do the math, last year the bees began to raise brood around Feb 28 or so (approx). This is when they need the extra pollen for precaution.
I think that the weather this year has been colder than last year, so I don't even anticipate that the bees have begun to raise brood yet. If they are, it would be slight. Probably in at least 2 weeks time though bees should be starting in a big way, no sooner. The days here have been warm, right Steve, but it has dipped to several degrees below zero at night now. See today is cloudy, the temperatures will be warmer.
Your hives are in the shed that you built. That should provide quite a bit of protection from the wind and other elements, that is good. When the bear knocked over the swarm, was it outside the shed temporarily? He can't get inside the shed it seems to me. Darn those bears. YOu should see the bear fence that I have to protect mine, literally a fortress, but after 2 seasons, no bear attack.
I didn't quite get which colony you added Ron's queen to. If it was the issued swarm, that queen that was in the issued swarm would have killed the introduced queen for sure. If you added the queen to the old colony that had the swarm issue from, the queens that had not hatched yet (and there probably would have been several, if not many queen cells ready to hatch in a few days after swarm issue) may have hatched at the same time that the introduced queen was released and there would have been a mortal fight. Or maybe this queen would be released quickly and go and kill the other queens still in their cells. Regardless, it sounds like it worked out OK either way, you had good brood pattern. Great day.
