Hi and welcome to BYC! So glad you joined us. Looking forward to hearing the stories of your chicks and seeing photos!
There are never too many questions. Ask away. There are LOTS and lots of folks here who have years of experience and are eager to help.
The kind of feed and how much they eat is going to depend on the breed. Bantams will eat very little. Broilers will eat like elephants. Most other chickens are somewhere in the middle. So...what kind of chicks do you have, and how old are they now?
I use a chick starter feed from my local livestock feed store, but it's available at any farm store, Tractor Supply, or similar outlets. They need "chick starter" by any brand name to be sure they're getting the proper balance of nutrients and minerals. (If you have broilers, you'll need something much higher in protein, like a game bird starter/grower feed.)
I found this resource on the Wayback Machine - The
Poultry Management Reference Manual, by Pennsylvania State University:

Scroll down to about page 5 or 6 for the feed tables.
If your chicks are a standard size breed, all six of them will probably consume about 30-50 pounds of feed total by the time they are 8 weeks old. If they are broilers, count on at least 60-80 pounds of feed.
For bedding, I don't use anything until they are 2-3 days old and I'm certain they are eating and drinking well. They just have a liner of paper towels. Then I use a thin layer of pine wood chips (med or large flake), but I also give them a dish of chick grit in case they accidentally consume some chips. Usually they won't. Some people use hay or straw instead.
Tip: Put the feeder and waterer up on a scrap of wood or something, to raise them up above the bedding. Otherwise they'll scratch around and fill both with wood chips. I use a couple of small tote lids in my brooder.
