FlemingOutdoors.com, StrombergsChickens.com and ChickenWaterer.com are online stores that sell automatic waterers for poultry and a range of non-automatic feeders. GrandpasFeeders.com sells automatic poultry feeders, and Amazon.com sells automatic poultry feeders and waterers.
GrandpasFeeders.com's automatic chicken feeder has a special lid that covers the feed and is opened by the weight of the chicken as it steps on the platform to feed. A soon as the chicken steps off the platform, the lid closes, protecting the feed from wild birds, mice and rats. The Precision Pet Wood Treadle Chicken Feeder, sold on Amazon.com, works in a similar way. The automated poultry waterers attach to a standard garden hose and have an automatic float that controls the level of water, preventing spillage or overflow.
