Have you actually looked at the nutritional value of corn? The actual values will depend on the type of corn, when and how it is harvested and stored. I think these are fairly representative values of the corn we would feed out chickens. The information did not copy as nicely as I'd like, Neither did the link. I'll copying a link, then I searched for "Corn grain, yellow. But do your own research. People are more likely to believe their own research anyway.

This is based on a serving size of 166 grams. A lot of those percents are based on daily values for humans, not chickens, so don't be too misled by that. As you see, protein provided is 16 grams so corn is about 10% protein. But like any other cereal grain corn also provides a lot more, including minerals and vitamins. It is not just protein. There is a reason corn was one of the "three sisters" grown by many of the Native American tribes. Carbohydrates were part of that but not the only reason.
I'm not saying that corn should be a major component of their daily diet. Like everything else, it should not. But you might want to check your facts if you think corn is "pretty devoid of nutrients".
