ration feeding is a great method .
mix grain with corn is not problem .like you said ,the corn is in a small portion .
how many time you feed a day ?
chooks man
We like to feed twice per day, once in the morning and once in the evening. But where we work we usually can only get one feeding in per day. They also scratch wheat straw and get scraps (bread, dry cereal, table scraps, etc). They are all healthy, but not fat.
If we put their feed in feeders, they get pellets only because they like to only eat the corn and grain and leave the pellets if they had a choice. lol
