The "queenless roar" is much more obvious to me with a large colony that is queenless. That means there are no longer any larvae less than three days old, and they have very little chance of rearing a queen without some intervention on my part. If there is any possibility that they can rear a queen, or are doing so, the queenless roar might not be heard. If they are busy with a strong flow, they might also be a bit distracted. I had a small late swarm acting that way - no queen, & no possibility, so they were just packing in honey.
I have one new queen unit where they rejected her & started their own cells. They are in an 8 frame medium box. There is a slight "queenless buzz" but the most obvious thing is their more agitated state.
I've had a couple small nucs rear nice mated queens this year. I started them with 4-5 medium frames, total. Some were from from a failed package, and a single frame of eggs from a good queenrite hive. I made up two "5 frame nucs". It was "swarm season", so there were plenty of drones around. Everything went like clockwork, and both are now filling a second 5 frame box, and providing donor brood for other needs.
Another package that failed has repeated refused to accept frames of eggs & young larvae, or the odd frame of brood with capped queens cells that I've come across. It seems no matter what I've tried, short of combining them with a strong hive, has worked.
All we can do is keep trying, and realize that sometimes it works, and sometimes it doesn't.
