What I'm trying to do is get away from the GMO corn & soy, which is a high % of the grower feeds. so I'm looking for something to boost the protein a bit; guess I may have to bite the bullet and have the feed store order some organic for me.... Glad to hear that on your brahmas and orps. I'll be hatching some orps out as soon as these pullets are further along.
Here's a thought for you. I order my feed from a feed mill that mills their own feed rather than ordering pre-milled stuff from other sources. You might want to check around your area to see if there are any feed mills. To avoid GMO, I have 2 options. I can either order organic or order non-GMO but not organic. They will make the recipe to protein percentage based on what I "don't want" in the feed. I specified "soy-free" and they gave me a few options for content at the protein percent I wanted.
The negative thing was that I had to minimum order 300 lbs (!) and I have very few birds. The positive is that I put out a note on the "organic chickens" group on yahoo to see if anyone was in my area that wanted to share. Someone replied immediately and we've been sharing "happily ever-after".
Your local mill may not have that kind of minimum, however. Worth checking it out.
