Feed for chickens is a moving target.
For baby chicks, you need a starter feed that is high in protean -- upwards of 20 to 25% protean. It needs to be ground very fine. Do not use layer feed or any kind of pelleted feed, as layer feed is high in calcium and that's brutal on their little kidneys.
Once they are 5 weeks old or so, you can switch to a grower mix. Grower formula is a bit lower in protean and higher in carbs -- basically, a higher percentage of corn. Once they are old enough to leave the brooder and move into the coop/tractor, they'll also be able to forage a bit. I'll throw a few more leftovers into the tractor for them to peck at, as well as fruit and veggie scraps.
As they get close to 6 months of age, switch them to a layer formula. Layer mix bumps the protean levels up a bit, and also if fortified with calcium which is necessary for egg production. People usually give the girls some crushed oyster shell as well. Layer feed tends to come in pellets. Their adult bodies have full-grown gizzards that enable them to digest it, as well as large bugs and other stuff that they'll forage.
Best of luck.
