A process for raising roosting fowl includes subjecting newly- hatched fowl to infrared radiation for a limited period of time and decreasing visible light. The fowl mature in substantially total darkness. Temperature is controlled to keep the fowl comfortable. The fowl are given a protein rich diet for a time sufficient to allow substantially complete bone structure formation, at which time they are switched to a high carbohydrate diet to increase meat weight. The process reduces stress on the birds and keeps them docile, resulting in decreased handling, faster maturing, increased meat versus bone ratio and increased bird numbers per area of raising space.
