I have 24 hens and 3 roosters (and one 12 week old that I'm almost sure is a rooster).
I have two separate run/coop setups. My older roosters, Bernard and Poppy, live in one with 13 hens. For a while I had a chicken wire "wall" that separated two halves of the run. They always free-ranged together and did well. Just this last year (after years of being separated when inside), I opened the door between them and they are doing well as one big group.
My other rooster, Monroe, is only about a year old. He's more aggressive, and so he lives in a separate run/coop setup with 4 hens. One of the hens had chicks (one of which I think is a rooster). I got 4 more chicks (sexed!) for another broody to bring up the hen ratio. I'm currently working on constructing a big addition to their run in case I need to let the maybe-rooster have his own separate space.
14 hens and 4 roosters (~3-4 hens per rooster) seems pretty low as a ratio. I've always heard it should be about 8-10 hens per rooster. It sounds like you have a good amount of space, which is good.
But like I wrote, having my roosters have their own "space" when it came to being locked up really helped keep the peace, and they mostly stayed away from each other when free ranging. (There were some minor scuffles, but no real out-and-out fights).
