I agree that in part it just depends on the roo..
I had a BR that was horrible, would chase my daughter in law from her car to the door and spured her a couple of times....
My most passive Roo is my FCBM..........I named him Gershwin.for the song Rhapsody in blue......
I also have an AStro, 4, 1/2 english Orps,and our main man, Boots, who came from a petting zoo.
We think he is FCBMs also. All of my roo's get along and all are great with us.......
My vote would be Marans..........
The BR came after me one day and Boots ran him down and took him to the ground........
We named the BR crock Pot.He is no longer with us .
Oh, almost forgot Bellino..1/2 cuckoo marans 1/2 penedesenca.
Sorry, a
little chatty this mrning.
Good Luck
