Oldtimer has given good advice, albeit based on "it all depends" - which of course is absolutely appropriate.
I notice you've already invested several frames of brood on this colony, and as yet still have an unclear result. I've had this happen to me a few times, when something goes wrong with the requeening of a colony and it becomes unclear to pin-down exactly what - particularly, is there a virgin still present ? (they can be exceedingly difficult to spot)
At some point difficult decisions need to be made - especially if substantial resources have already been donated to that colony. Is it worth investing any more resources ? Is that colony worth saving now anyway ? What complications can arise if a virgin (now 'out of time') is still present ? It's a tough call, and there's always that temptation to add 'good money after bad', so to speak.
It might be a better plan, for example, to use some resources to start-up a new nucleus colony, rather than plough more into this old colony - then, when that nuc is fully functioning, add this old colony to it by a 'stand-swop' - to absorb it's foragers, and then combine the remainder of the bees 'through the front door' via a shake-out, in order that it's guards can deny a virgin or any laying workers entry.
