All 3 of your above mentioned feeds are foreign to me as I am in Eastern Canada. Personally I do not use organic feeds either as they are probably pricier. I use poultry grower mash and or lay mash as it has a little bit of everything in it. Crushed pellets, cracked corn, barley, etc.This is a well rounded feed.
I stay away from just feeding pellets so I lessen the chances of my birds developing sour crop.. That in my books is so much harder for the birds crops to break down and a grower mash and or lay mash has much smaller pieces and a lot easier on the chickens digestive system. Some chickens are very fussy about their feed and you may have hens that really don't go for just pellets and they may steer away from eating as much as they should. A mash mix gives them a variety at least. Steve
