I'm stumped by one of my nucs.
It's a 5 frame 3 deep colony that was a spring split that was very successful and is full of bees. I decided, given its strength, to overwinter it keep it as a colony rather than combine. 2 weeks ago the bottom deep had some frames with some open/hatched brood and the queen seemed to be slowing down. I put that box up top and gave them some 2:1. A week later I found capped queen cells along the bottom of a frame, and couldn't find the queen. I was surprised that they'd want to swarm given the dropping temps but figured it must have been the feed tricking them (only 1 gallon of 2:1..). I checked yesterday and the QC's are all broken down and I found a queen. Unfortunately I didn't mark this colony's queen.. so I don't know if this is my original Q or a virgin. She was a good size though and moving around pretty slowly, so I'm thinking she's the original. I don't see eggs/larvae, just capped brood. Loads of stores, and still lots of bees.
So, the hive doesn't look like a post swarm hive. Could this just be they replaced the queen? (ARe the QC's usually on the bottom like swarm cells in that case?). And, it this is indeed a new queen I'd imaging that in eastern PA now the chances of her mating are slim to none.
I figure I'll just let this ride and look for eggs next week.
If I don't see eggs/larvae should I just combine this with another nuc or just let it ride?
