from my experience if there is more then one rooster in a flock they will fight to see who is top dog, but my barred rock and silkie [ building a new enclosure soon wont be in with big flock then] roosters crow at same time????? i have one other bantam rooster who is mating with the girls in front of other two but they dont seem to annoyed!!! any answers to these behaviours would be hugely appreciated!!!
