Yes, remember my pic of the communal broody pile? Mine sat on turkey eggs even.
Though humidity levels of her body vs a chicken may come onto play.
If they hatch I would remove them. Even without the worry of water ducks raise their young so different than chickens. They might not learn to scratch and peck in a normal manner.
The chicken hen I had that raised a duckling tried her very best to teach it how to be a chicken, but while she would show her how to scratch and hunt for food...and all the chick siblings would follow suit, duckling would just stand there dumbfounded...like she was saying "Uh, mom, my feet can't do what your feet do, and I don't have a pointy beak!"
My chicken successfully raised duckling up, a muscovy, but it never really fit in with the other ducks. I kept everyone together in a large flock, but duckling grew up not acting like a duck, but not acting like a chicken either. Neither group wanted her once she was big.
