I feed a 24% protein feed from day one. Adult birds get the same. I add some essential vitamins and minerals and some grains to the feed,ie; selenium, L-Lysine, Vit E, Krill oil, Vit A and B12 complex, Black oil sunflower seeds, milo, flax seed, rolled oats, parched barley and red winter wheat to name a few.
I belive I get healthier chicks, on the whole, than I would if I used a commercial feed. I use Nutri-Drench in there water for the first week of the chicks lives. After that they get the same well water I drink. The few times I've had chicks hatch with wry neck, I was feeding a commercial feed.
Some people don't like corn as the main source of protein because of the GMO factor. I don't like Soy as the main source of protein. This is why I add the extra stuff to my feed, it's more expensive but then again I have some rare and expensive birds, which, I feel I owe them the best possible life and nutrition I can give to them in an enclosed environment.
This is good information!
I will try to tuck all this into my little brain - NOT!!

These birds are beautiful and I always thought they needed "extra care". It's sounds like I'm right. They are not for me, but I love to look at the photos and learn a little about them along the way.
