I have 4 hens and one rooster. Not advisable as far as rooster to hen ratio but I seriously down sized to only my favorite chickens once we started showing Ripley. Its been so much easier than the close to 30 we had. Just enough eggs for us to get a dozen or two a week and the poop cleanup is manageable plus we can leave feeders out for them while gone and water and they are fine. Fortunately, my rooster doesn't beat them up. He does his breeding in the morning and at dusk and is good. Young roosters will be horndogs... mine is about 2-3 yo.
I would advise getting pretty chickens and enjoy them. Don't worry about egg producers unless you are wanting to sell for profit. Buff Orpingtons are nice and docile, so are my Ameraucanas (read, Ameraucana and NOT Americana or easter egger). Basically purebred breed bred to a standard

. My Ameraucanas have all been basically lap dogs with feathers. My rooster is an Ameraucana and he NEVER has looked at us funny. He will keep his distance but isn't mean. I also have a buff Orpington hen and blue laced red wyandottes that are big girls and also docile, not lap dogs but not afraid of us or mean either.
I would recommend finding a breeder (you read that right) if you are going to purchase Ameraucana chicks, over going to the box store. If you are going to go with hatchery stock, skip the box store and order directly from the hatchery and have them shipped directly to you. McMurray and Meyer Hatchery are two big names that sell quality hatchery stock.
Build your coop larger than you think you need. Chicken math is real and it doesn't hurt to have more room than not enough. If you ever can't let them out due to vacation or bad weather, you won't feel bad leaving them in if they have plenty of space. Too little space causes pecking, fighting and injuries. But... 12x12 you have more than enough space for 8 chickens lol! You theoretically have 18 chickens and leave them inside with that much space (or more if you let out every day). Obviously fresh air and grass is better but being locked in occasionally will not hurt them. They say 4 sq ft of coop space per bird (if you are letting them out daily) and 8-9 sq ft/bird for run space, but the more the better. Also if you don't want to be early to rise or might come back late, they do sell automatic coop doors that open and close dawn/dusk.
Mine free range with no aerial cover so I wouldn't free range mine without a rooster among them. He is their first line of defense. He will be the first to alert them to run for cover and will be the one to sacrifice his life over losing one or all. Mean roosters do their job very very well but horrible for management. Think boots, pants and a good stick to be able to access anything, and never turning your back. Many don't tolerate mean roosters and dispatch them while others want them for heavy predator protection. Just know, every one has predators. It's just a matter of time of them finding your chickens so when you build, build with that in mind and fort Knox your coop and run.
I leave my auto feeder and waters inside so I know they always have access even when I can't let them out. Some people don't like that due to rodents but again... fort Knox. Never had a rodent in the coop.
Speaking of mean roosters, are you willing to dispatch any or cull a sick hen? Yes, try to save one with supportive care however there aren't many vets that will see a chicken, so be ready to cull to end any suffering before it goes on for too long. It's sad when people aren't willing to end their suffering and let their sick chicken slowly die after all options have been exhausted...
Woo sorry for the book ... as with anything I don't own an animal without extensive research and diving in absorbing everything I can about them. I'm happy to talk chicken, maybe too much...but no surprise there
