Can Ducks be with baby ducks and not get stressed

[Farms352]

So I have 1 8 month old Female Duck and just wondering that if she will get stressed if she is with 2 baby ducks?

I wouldn't worry about stress of her moreso the stress of the ducklings, plus her being older she could end up bullying the ducklings. Any chance you could house them separate until they're older?
