I'm using an incubator now, with high fail rates, still dialing things in. Your plan should anticipate very high losses early on, and moderate losses once you have the kinks out. We had 100% loss on our first five duck eggs, and the incubator was tied up for a month.
Started 12 chicken eggs after that. Two discarded, infertile. A handful showed some development, but the shell is so dark I can't see movement, so *fingers crossed*. Two lighter shells, definite movement. I'm just over two weeks in on a 3+ week commitment and already looking at 84% success best case. Power outages, big humidity swings from weather changes, there's all sorts of things can go wrong.
its not a panacea either.
Breeding is serious business. You can do it that way (if you have the space, time, and resources). If you don't, best you can hope for is selective culling - that's what I'm doing. Slower, less control, but I don't need as much breeding stock, or to keep my breeds all separated, introducing and removing roosters as needed. Eventually, you can wind up with a flock well suited to your needs - but you won't be selling them on Craigslist for anything like what a breeder can get for a pure bird, and you won't be winning any 4H and County Faire Trophies you can show off to prospective purchasers.
Not to dissuade you, just to prepare you for heartbreaks and encourage you to be flexible.
