They sure can! I have them under plum, apple and pear trees that produce much better with the birds underneath. I like a mixed flock of muscovies, chickens and turkeys. The main caveat for mixing them would be to have enough female ducks (4:1 at least) to males to reduce sexual aggression towards the chickens. Spanish cross turkeys can take care of themselves and are excellent sentries for raptors and raccoons.
This is all just my opinion based on a flawed memory
