Thank you,
@MauroBBQ !
I don't think that rotating the birds would be necessary.
However, it's your cook-up, so you may want to experiment a bit.
As far as the temperature ... ?? Honestly, I have no idea.
For a cook-up like this, I don't concern myself with the temperature of the cooker, I just let the kettle take care of itself.
I would be more concerned with the internal temperature of the meat.
And, yeah, I would say about 1 - 1.5 hours at most for these small birds.
All the best with what you end up doing.
