Well I am going to be the bad news (haha, not and enabler) A lot depends on where you are, and how lucky you are. What you need is a couple of plans, at least A and B.
If you live away from the equator, in the northern hemisphere, the advantages of free ranging will not compensate for too small of a coop. In the north, the dark hours of night will artificially confine your birds somewhere between 14 -16 hours a night. Mine in SD are roosted by 4:15 in December, and not coming off the roost until 7:30 ... in good weather. Bad weather can really compound it.
The thing is, roosters can get along just wonderfully... until they don't, and then they can fight terrible. Sometimes they fight once, and get over it, and sometimes they will fight continuously, even to death.
 They can be darling pets... until they turn into demons attacking children first, then women, then men as they get braver and meaner.
The plan B is how to separate them, and where to put the fighting birds, and plan B needs to be previously set up, so you can do it immediately. A dog crate and a 5 foot fish net can work well.
Maybe I will be an enabler, if you get rid of two roosters, you can get more hens! and still have everything thing fit in your set up. The thing with chicken math, is it has to work both ways, additions and subtractions. I work at enjoying keeping a flock, the individual birds come and go!
