Maybe.
I had a similar situation except my two Roos were in a flock of new chicks, all the same age. Dominance of one was obvious early on, but as the more slowly developing Cochin caught up, I think it occurred to him that perhaps he could be The Man. Around 15 weeks (adolescence?) he got very nasty towards several of the hens, to the point I seriously considered rehoming him. One morning, out of frustration I grabbed him by his tail feathers and tossed him into a large wire dog crate that was set up nearby. He was incarcerated for three full days. The other chickens walked around him, looked at him, sat on top of the crate, poked through the wire to steal his food. It was the equivalent of being in public stocks.
Honestly, I was using this time to find him a new home, but when I let him out to walk around a bit, it was as if he’d been to reform school. He’s turned out to be the top rooster, but he and #2 are amicable, and he’s the more gentlemanly of the two. He’s incredibly roostery in his flock tending. I’m glad he got a second chance, especially since it was unintended.
Was the change a result of the timeout? I don‘t know for certain but I like to think so, at least in part. All flock situations are different and the variables are countless, and every bird’s personality and aptitude are unlike any other, so anything is possible.
If you can take the time, there is a plethora of rooster information on BYC - the threads are innumerable but search the articles for more concise reading. You’ll find a spectrum of divergent philosophies, and hopefully some will help guide you and your boys.
Good luck! Those are some handsome Roos!
