Is it safe to let a duck raise her ducklings in a mixed flock?

[FowlPrincess]

hi. I have a mixed flock of ducks and chickens. My chocolate runner duck decided to go broody and has been on her nest for about 3 weeks. Is it ok to let her raise them within the flock or will the chickens peck the babies?

Thanks!
