Okay. Take a nice, deep breath. In-2-3-4. Out-2-3-4. Good job.
We were all once new to this, just as you are. And all the resources can be overwhelming for sure. But don't panic, you can do this.
Like Ridgerunner said, reading on the forums can be info-overload. Many of the folks on here have been keeping chickens for years (if not decades) and have accumulated a lot of nuanced knowledge along the way. It can be hard to sort through if you're new to this.
Congrats on ordering your chicks! Some questions below so we can help you more specifically:
How many chicks are you getting?
What breed?
Are they hatching locally or coming in the mail?
Do you have a brooder for them yet?
What's it look like and how big?
How about a coop for when they get bigger?
Even if the only thing you have so far is a receipt for your chick order, don't panic, it's not too late.
Chicks are remarkably hardy as long as the basics are taken care of: shelter, heat, food, water. Okay, the details are a little more complex than that, but not by much.

If you can give us some more details on where you are (geographically) and what you've got so far we'll be able to help you keep going in the right direction.
Just hang in there and take it one step at a time.
