Is it normal for my dogs to bark whilst chasing each other on a walk?

For context i have 2 cockapoos who are 3&4 years old and a WCS who is 1.

Whenever we are out on a walk these days, my WCS is much faster than the other two, and they like to chase her (she also enjoys this and encourages the game!). However, when they are chasing her they bark bark bark until she stops and/or they catch up with her. Is this normal? I don’t want to punish them if the are only having fun (and i can tell the bark/body language is not aggressive, they are all very happy whilst chasing each other).

I think the reason it concerns me is because both of my cockapoos can bark reactively sometimes. it is something we have worked on at great length, and is much better than it used to be, and still working on it too! But now and then they can bark at a passer by at the window/a dog across the street.

Should i be trying to stop the barking when they are chasing?
