Diard's Fireback is another name for Siamese Fireback Pheasant. When feeding cracked corn or peas, it is recommended to use PECkOMATIC Automatic Feeder's ½-inch regulator disc to feed these pheasants. If feeding corn, the 1-inch regulator disc can be used. The opening ensures the easy flow of feed. It is wide enough to regulate the flow and it does not clog up the feed.
