Quote: Weeeell, I would not exactly agree with that. It's not like corn has absolutely no nutritional value. It does. It just has too much fat and too low protein to be the largest portion of a chicken's diet. And, as I said, there are different formulations of scratch. Around here, I can get plain corn, 3 grain, 5 grain, 7 grain, 11 grain and 13 grain "scratch". Those certainly have nutritional value.
The picture I posted above is an 11 grain game feed I use as my scratch and it does have good nutritional value, just not enough protein or calcium for laying hens on a daily basis as their sole ration, nor for growing chicks.
