How soon to replace swarm queen?

[Angularity]

The queens with the three swarms I have collected this season all seem to be laying, but I am aware that they will need to be replaced at some point.

What is that point? As soon as practical, going in to the Autumn, or some other point?

I wouldn't replace them! Not if they were laying well and good tempered. The bees will tell you when the time is right!

Check the brood pattern generally and temperament of the bees, builld-up etc and assess them before making a decision. Your swarm queens might be fine. If you just want to have different queens - say you keep only carni's, then any time is suitable - at your convenience....
If the queens are OK and you want to get rid anyway, then your local association may have someone who has need of them.
