Rooster keeps attacking my Turkey!? >:/

[inermotion]

Ok this is getting quite ridiculous, Our rooster keeps attacking my turkey every time I put him outside, The turkey is about 2 months old now & almost big enough to defend himself but today & not just today the rooster managed to sneak up to my turkey while I was changing his bedding & when I came back the rooster was chasing my turkey across the yard in circles biting & scratching with his feet & my poor turkey didn't know what to do =(
He used to be a nice rooster until he reached adult (4 months old now) & has been biting the female chickens & plucking hair out of them & now he is attacking our animals including the chihuahua. I don't want to cull him because we need him for breeding. Is there any way I can stop this behavior? He has no problems being around people, just animals.

I would not breed an aggressive rooster. It just passes on bad behavior to the offspring. Too many good roosters out there to keep a mean one.
