I have been thinking about mixing my own feed. Locally I can get 48% soy pellets, whole oats, wheat and cracked corn in 100 lb bags. When I mix that together, it will yield a 21% feed, completely made of cereal products grown locally. By messing with the mixture ratio I can get a 16% feed, and a much higher % feed for gamebirds and such. My question is: By using the above cereal crops, am I ok using them? I've never heard of any adverse effects from them, I just want to be sure. I can make 400lbs of 21% feed for a total of $65.05, much cheaper than buying if from the store.
