Welcome to Backyard chickens. Do you have an incubator? Have you ever hatched eggs before? I'm asking because a lot of people would rather buy chicks, than go through the process of incubation and hatching. Even with local eggs, there are time people get poor hatches or none at all. Plus if you get males, you have the problem of rehoming extras, in a market that is glutted with cockerels.
I am not trying to discourage you - just make you aware that there is no perfect way to get eggs, chicks, hens etc. They are frequent "Hatch A-Longs," on BYC and if you follow them you will find out what others are going through and what advice works for them. There are also quite a number of articles on hatching and incubation - that you can find via the search box.
I have not incubated/hatched chicks - so I am sure others can give you more information.
