How old until I have a problem?

[Xovan]

I have 40 chickens right now. 3 speckled sussex roos, 1 speckled pullet ans 2 red sexlinks that are 4 mo. old. and at 3 mo old, an assortment of wyanddotes. SR with 6 NN thrown in 4 roos 2 pullets. right now I do not have a problem but I know one will come. I plan to keep 2 roos and 20 pullets. But at what age will the fighting begin. I know there is no specific answer but a guestimat will help.

well i have 3 roosters to about 13 hen( I have some in the brooder to add more ladies) but none of ours fight in fact two of them are like best buds. they patrol the flock together and the other one has a little flock of his own of about 4 hens that do their own thing. so honestly... i think it just depends but ors may chest bump every now and then but don't really fight per say.
