I was given about 75 pounds of livestock quality wheat. I also have about 100 pounds of oats already, and about 100 pounds of black oil sunflower seed. How do I serve this to my chickens? Does it have to be ground first? Is this a "treat" ration (I KNOW that BOSS is considered a "treat", but what about wheat or oats?), or is this to be served as part of a regular ration mix? If it should be served as part of a regular ration mix, what else should I mix in to create a balanced diet (keeping in mind that I WILL NOT give my chickens GMO corn or soybeans)? Do these grains have to be ground, or can the birds eat them whole?
