How old are your kids? If your kids are under the age of 5, and share the yard with the chickens, I would strongly recommend waiting a couple of years to get a rooster. Some roosters can be aggressive, and they tend to attack children first. Personally, I recommend waiting a year with just hens, so you get some chicken experience. Roosters are a crap shoot, some are darlings, some are nightmares and some go from the darling to the nightmare in an instant. Roosters have ruined the whole chicken experience for a lot of kids.
A rooster will also change the dynamics of the flock with you. A hen only flock is much more approachable, they look to you for food and protection. A flock with a rooster, will look to the rooster, and the rooster will mostly be between you and the flock.
I too would wait until your hens are older, and I would get a local rooster, whose nice disposition has saved him from the soup pot. Do know, that often time, hens with a rooster will be barebacked due to mating. Some people do not like that appearance.
I am in the camp of wait to get the rooster for another year. You and your family have years to enjoy this hobby, work into it gradually.
