Getting 4 chicks tomorrow...

I usually feed mine non medicated feed, but that's due to the philosophy we carry of "if it's not healthy enough to live without medication, it's not healthy enough for our flock". In the beginning you want a 10-20% protein feed. Anything higher is usually reserved for meat birds, but it won't hurt if the food has a higher amount of protein. Around 18 weeks, you can start feeding layer feed which is about 15% protein and high calcium. Also add a bit of oyster shell in there to supplement the calcium intake if you like. We also throw in a handful of flax seed for Omega 3s. Have fun with your chickens!
