I have 8 (7 week old) chicks and 3 ducks (aged 2-4 weeks). One of the chicks is definitely a cockerel, and I am pretty sure the smallest chick is also a cockerel (although it could just be an aggressive pullet). Also, I think one of the ducks is a drake. I have a few different breeds of chicken, one of which is buff orpington (I have 2 pullets). My husband and I would like to breed the buff orpingtons only and have begun looking for a single buff orpington rooster. However, since all of our chicks and ducks currently get along great, will the addition of another rooster definitely create havoc? Or is there a way to make this work with the male/female ratio I have. If not, is it better to rehome one of my other males in order to get the BO?
