I just requeened a mean hive like that, but through the excluder didn't work, I went back and shook them all out, and put an excluder on the entrance. check it out: https://www.youtube.com/watch?v=OR7rxF0fkGo&t=247sWelcome to Beesource. Straight and to the point, how do you know your hive is queenless? At this time of year, lack of brood or eggs is not an indicator. On the other hand, if you know because you rolled her, or had a late season swarm, then AFAIK you can combine any time it is warm enough that the bees are not clustered. Might be getting a bit cold at night up there.
Even if you are certain they are queenless, it wouldn't hurt to run them through a queen excluder before combining. Just to be sure.
I have had something similar happen so now when I do a shake out I do it 30 feet or more away from the original hive location. I have spotted queens walking up the side of the shaker box. I also now use an additional deep box above the excluderI went back 5 days later and they were rejecting the queen and roaring, the old queen must have flew in the entrance or something, so I put an excluder on the front and dumped them all out again, this time it worked, they released the new queen.
