you might witness small fights of which are considered 'challenging.' Challenging is something that almost all cockerels will do

I am "Lord of the Roos".. hehe.
My Freezer Flock only challenges each other for very brief moments. All are similar ages/batches.. One group of 20ish roam and feed in harmony. With the occasional pecking challenge..
As long as they are not caged and the loser of the challenge has plenty of room to back off. Multi roos need a multitude of space.
BUT having more than 1 Rooster with the ladies means the ladies will be double tagged and tore up more.
