I've been reading a lot about soy, and I REALLY don't want to feed it. But I need a complete protein grain, or grain + legume. I was originally thinking about quinoa, but that's so expensive, if I fed it, I'd get around 3 dollars return on my chickens at best, against 25$. I need protein for my chooks... What other legumes/grains can I feed? Right now, I'm giving them corn and wheat, plus this instant quinoa stuff I HATE. My chickens love it. They also get a handful of cheese and salad and dried fruit. They free range for buggies. Am I missing anything?
