Soybean meal here in michigan is 47% protein and I have used it for over 50 year without any kind of problem and the meat scraps I use is 50% protein and never a problem with it either. I buy Fish meal at local feed store and it is feed grade fish meal. I never use more then 5% fish meal in my ration. I figure if the soy beans are good enough for me then they should be good enough for chickens and I have no worrys at all eating or using any of this.
