Can roosters ever be succcessfully integrated?

[magentamomma]

i now have 2 really bloody beat up roosters. It is really sad. one tried to back off and i thought it was over so i left them but when i got back they had been at it again, cause the new guy was bleeding all over again. i put him up seperate for the night, but we'll try again in the morning. i hope it works out.
