I feed my hen and roos whole corn and layer feed. I toss bunches of feed at diferent places to give everyone a chance to eat evenly. I am not liking the idea of my chickens eating from the soil since wild birds come and visit their run. If I put a tray they fight over it. I was thinking making a 22 holes in a 2 inch 8ft pvc pipe? Any suggestions or ideas. Thankyou
