What to feed them next?

[Chaos18]

I have 7 chicks (6 girls and 1 boy). When I bought them I also bought some freshly ground chick starter feed. Chicks are currently the ages of 3 weeks (3 girls and 1 boy) and 4 weeks (3 girls). In roughly another week I will run out of the freshly ground stuff I bought when I got the chicks. What should I feed them next that I could buy at Agway or Tractor Supply or some similar store?

Any other chick starter or chick starter/grower really. The brands will vary based on your location.

More chick starter or a flock raiser (good for birds of all ages)
