The first brooder produced by Shenandoah in 1924 was coal-fired. Since then Shenandoah has become the leading manufacturer of gas brooders in the United States with the largest variety of models and options available. Extensive testing and research has led to a full line of gas brooders ranging from a standard pancake brooder to the newest technology in radiant brooders. Our dependable space heaters provide warm air heating as an alternative to brooders.
