Wow, that's a pretty good deal! I agree, though, I wouldn't want to risk a quarantine running into wintertime. Those are no fun! Here's hoping one of the remaining two turns out to be a good rooster for you!
My main flock consists of Reuben and Winter, plus all of the hens. I don't rotate roosters as Reuby has proven himself a good flock guardian and not too rough on the hens, and he tolerates Winty so I leave him, too. Roscoe is hot and cold with Reuby, and ended up separate after some battles that turned bloody, but was good with the girls so it's only for fighting with Reuby that he's not in the main flock. The rest of the boys are big and a risk to my bantam hens, so they are in the rooster flock, or separated on their own if they don't get along with the other boys.
My setup for them right now is that I have three 4x8 foot rooster pens, one of which is divided into two 4x4 pens. Once I send the freezer camp boys to process, I intend to move Roscoe and his boys to a larger pen so that I can rotate them and the other rooster flock in the rooster yard for more space. I'm pretty sure, since Roscoe and crew are bantams and the rest are large fowl, that I won't be able to group them all together safely, so I think this is the setup that will work the best. Then the remaining two 4x4 rooster pens will be used to house Ben, who doesn't get along with anyone but stays as the potential replacement if anything happens to Reuby (Ben is Reuby's son), and potentially Tygo because he doesn't get along with the boys but I haven't decided if I want to send him to the stewpot with the rest of them.
I feel like I'm rambling--I hope that answers your questions!
