We have a couple of sacks of soybeab meal left over from mixing grain for our cattle. It looks like lite small lite brown flakes, not like flour fine but like baby cereal fine. I have read other threads about the use of soybeans but no one ever cam outrite said it is ok to add to feed. Doea anyone know if it is? I mix my own feed for the chickens and duck which is unscientific, I just mix till it look right. Whole wheat, cracked corn, laying pellets, black sunflower seeds and white millet in addition all the scraps from the kitchen. Would the soy be overkill? Thanks.
