Firstly, I would find a breed that goes broody a lot and is known for its good parenting. I'm not an expert but I assume having several broody-prone hens will keep you from having to purchase a very expensive incubator.
Secondly, it depends on what your parents are concerned about with the rooster. If you live in the city and if they are concerned about crowing because of neighbors, you can always check your city laws about roosters. If the laws allow roosters, then your neighbors couldn't force you to get rid of the rooster if they wanted to. However, if your parents are concerned about the temperament of the rooster, there are a few things they may need to know.
One, roosters are not often the aggressive, loud-mouth bullies that a lot of modern people seem to think they are. This false idea may be a result of the drifting away from our heritage roots, or it may be the influence of anti-cockfighting groups like the PETA or the SPCA who exaggerate the temperaments of cocks to keep people from having too many in their flocks. Either way, roosters are often mild-mannered and sweet towards people, depending on human interaction and breed. Breeds like the Chantecler, Silkie, and Cornish are good examples of breeds with mild-mannered cocks. Surprisingly, contrary to public opinion, gamecocks (especially Oriental ones) are very good with people and hens and are noted for their calmness around humans.
Secondly, good cocks are always good to their hens, especially if they are the only cock in the flock or if there aren't many other cocks. This feeling of superiority seems to make them chivalrous with the girls. However, in my experience, low-ranking roosters who are constantly being dogged by a dominant cock will tend to be mean and hormonal with hens. But this is just my experience. Also, cockerels who are going through "chicken adolescence" will tend to be hormonal and overbearing with females. By the time they are about a year old, though, they grow out of this stage.
I hope you can get started as soon as possible with your plans. Raising chicks is always a great experience. Having a few roosters (or even just one) is a joy as well.
God bless,
