That's going to all depend on them as individuals more so then what breed they are.
I've had many cochins that were super easy going but I've also had some that seemed to have the small chicken complex. They weren't scared to mess with the biggest rooster in the flock. Always seemed that they thought they had to prove themselves.
I've never had the luck with LF brahmas that others have.
The only rooster I ever had that actually wanted to fight to the death whenever he came in contact with another rooster was a buff Brahma.
Another time a bought three gold laced brahmas. Turned out to be a trio. Soon after they started laying the rooster killed one hen and severely injured the other.
