And what breed do you have? My older rooster can't stand his younger sonRoosters only crow in the morning. I have 8 currently disproving that.
That petting a rooster will make him more aggressive (own personal experience here, dudes a d*ck anyways but seems to behave better if I pet his back a bit while in his pen at eye level)
That you can't have more than one rooster in a flock (my two main flocks have 3 roosters each)
