Oh. Too bad. I agree that incubators can be pricey, and it's always good to try something at home. Sounds like you're a kid trying to learn, and that's good! I am too. Just keep at it.
People usually start out with chicks, because even with an incubator it can be difficult to hatch eggs (not to mention all the roosters that you may be getting!). So I would recommend getting some sexed chicks to start out with (this means they should be female). Then, after your flock has been established for a while, you can decided to get/make an incubator and hatch some fertile eggs, or add a rooster to your flock and hatch your own. It's a very rewarding experience and I'm glad you tried!
