can gamebirds live on nothing but whole corn kernels and dirt? im curious of some neighbors birds are just going to drop after to long, or if the can in fact live off this for many years, and ive been mistaken telling them they are wrong and the birds need alot more protein to a least feed crushed dog food, or chick feed with crushed oyster shell (theyll buy expensive birds, but not offer other feed, as say traditional)? i go by my hens laying every day, and roosters being really muscular, but they sa better game birds need to stay light and tough..
