Will my chickens attack ducklings?

[wildpeas]

My chickens attack any animal that comes into their yard, ducks, dogs, cats, geese.

My hens seem to be okay with any animals, I guess my main concern is my rooster! He has been getting somewhat aggressive towards my daughter and our dog. He doesn't bother the dog, but the dog tries to play with him and he attacks her, although the dog doesn't care LOL. Thanks for all the input! I guess I will just have to see what happens! I will hate for them to be seperated forever, and to be worrying about them fighting! I will be thinking about it more before I make a decision. Thanks again everyone! Have a good day!
