Question on roosters

[Sarasarasara222]

i have this old rooster around 4 years but he’s still strong and sassy, so recently he jumped over the fence into where a younger rooster was who was constantly singing and displaying dominance and a quiet young rooster just starting to sing and mount hens but he ignored the quiet one and the other young rooster challenged him so he hurt the young rooster badly but he’s back to where he should be. So I’m planning to move the quiet rooster to where the older rooster is but I’m not sure if he will kill him judging by the following incident, so my question is would it be fine if I move the quiet rooster to the older roosters flock and would it quiet down the young rooster that constantly sings?

My guess is that the older rooster will attack the intruder, but the only way you will know for sure is to try and closely monitor things.
