You can feed them raw or cooked. I just wouldn't give them too many at one time as they are only around 10-14 percent protein and they can dilute your overall daily protein. Minimum daily requirements are 16%. Feeding a higher protein ration than that 16% amount can allow you to add extras without causing deficiencies.
My baby chicks will even snap up race horse oats, like they were beluga caviar. By 7 days of age the little Hellions are even eating whole grain or shelled flint corn. That's Arginine flint corn, not Flint, Michigan corn.
