Whole dried corn? That's actually really hard for them to digest and not great for them nutritionally speaking. It should not be in a feeder for them to help themselves to.She gets whole corn. I have 11 girls and the corn is in a corn feeder. They all eat it plus the laying mash. I also give them snacks such as veggies like broccoli, green beans, peas, and fruit now and then like grapes (cut up so they do not choke), watermelon, apples, etc.
Cut out all treats, they should be less than 10% of their diet, over doing the treats leads to health issues.
