I was just wondering if any of you ever feed soy hull pellets to your chickens? The local feed store told me if they free range, that soy hulls is all they would need for extra protein. It's about 30%. I bought a bag and they seem to like it, but it has corn gluten in it also and they want no part of that. Is this acceptable to feed? It's about 1/2 the price of grower or scratch And I think I can get just the soy hull w/o the corn gluten.
