Had a copper maran cockerel here once I had picked up with various roosters for free to can up, kept him around a bit to get some size on him. The only rooster in my whole life that dared to lay a beak on me...bit me in the leg as I was walking away.
Two can play at that game, so the next time he came around the corner of the coop I laid him OUT. Thought I had killed him, so threw him over in the woods with a big ol' heave. Later on that evening I saw a bird come walking up the yard all crooked necked and staggering a little. From then on he was referred to as the undead rooster...and he kept a wide space between he and I until the day he was big enough for eating. Never offered to make fight at any human after that, so it does show that a mean rooster can be converted to a plain ol' human fearing rooster in one training session if one is firm enough.
