Cockerals and roosters all have their own personalities, so no one can say exactly how it will go. When I have observed males establishing dominance they fight on and off for a few weeks. Then there is a time when the "winner" doesn't allow the "loser" to be near him or his flock. Then after a few weeks the dominant male allows the other male to come back. (After he is secure in his place?) I have had some pair together, and others who have just had their own group of hens.
