I've been feeding a scratch I get locally. It $15 for a fifty lbs bag. I say it's local. I have to drive about 20 miles to get it. Anyway, I ran way low and bought a 25 lb bag of Purina scratch at a local farm store. I was dumbfounded at what was in it compared to the mill stuff. It is just about all corn. The other has all kinds of different seed in it. The millet in the mill stuff the chickens really pick out. Is Purina just saving money or do they really think corn is all that's needed? It nearly seems as thought they are just lazy and don't care.
