Last year I got a pair of Rouen ducks and loved having them. I sadly had to give them away and now I'm thinking of getting more ducks. I really don't want to have them in another coop for them since I have plenty of room in my chicken coop. My chickens were fine with the Rouens but that's because they were raised together. Would I be o.k. to slowly intorduce the new ducks to my chicken flock. I also have a rooster that can be pretty rough sometimes, so what is the likely he will attack the ducks?
