If it makes you all feel any better, my ducks throw some smack down on the chickens, head rooster and all. My pekin duck likes to sneak up behind him and give him a good goose, I swear they (the ducks) place bets on how high he will jump this time. I have had to break up one fight between my drake and rooster, so having a way to give each flock a bit of space away from the other is a good idea.
