You don't really have to take extra care when it comes to their feeding requirements. Give them regular whole grains, corn, rice, soybean, sorghum, or legume seeds. However, you must not feed them superfine or powdered grains. Also, make sure that the food is free of mold, pest, or any other hazardous element. Keep a corner where you can place the grains for them, so that they can feed all the time, especially, the young ones as they need a lot of food to grow.
