I feed Kalmbach 20% Flock Maker. It's not the organic version -- the store I buy it from carries their organic chick feed, but not this particular feed.
I really like Kalmbach. 20% is a good protein percentage, as I can toss them kitchen scraps or garden weeds and not worry about "diluting" the protein to any large degree.
Know that even in organic feeds, there are some additives that are allowed to be included to get certain critical amino acids into the feed. Methionine is one, and it's essential to a chick's development. There aren't plant sources that are rich enough in it. Thus the addition of a synthetic.
When I had chicks this last May, I feed my entire flock (including 1 rooster) Kalmbach organic chick starter. I slowly transitioned them all to Flock Maker and they all eat that now. I have oyster shell and crushed egg shell on the side for the laying hens.
