Would these seed blends + added calcium make for a good chicken feed or a base for a homemade feed? I'm wondering because we have a ton I can get at cost @ work. One is a three way blend. I think wheat, oats, clover (I think). The other is a 5 way blend. I want to say it includes pea & rape as well. I can verify the exact blend tomorrow. If I can use these as a base, what would I need to add to make nutritionally complete feeds?
