Is this because they are raised together? I have never been able to put any oegb roosters(mature) together unless they were raised together. Serama I could, but the oegbs would just fight, small coops not large onesThis simply isn't true. Old English large fowl? Yeah. But the bantams...there's never any issue. My males all live together when not being used for breeding, my more accomplished neighbor up the road pens his cocks and cockerels together too up to 30 of them at a time, never has an issue, course we might just be too new to the whole chicken thing, only 39 years between the two of us and only 37 with OEGB.
