Little need be said about the first principles in poultry raising, but a few introductory remarks about comfortable quarters for the flock may pave the way for the description of the straw-loft poultry house illustrated in sketches shown. It goes without saying that the laying hen must have comfortable quarters if she is to be expected to produce her maximum yield. Warmth, dryness and protection from preying animals are the prerequisites to comfort. The poultry house sketched here is a practical starting unit embodying all of the protection features so essential in poultry raising.
The importance of poultry-house ventilation is generally conceded, but just what is meant by ventilation and how it may be accomplished is not so well known. It is becoming increasingly evident that adequate ventilation cannot be accomplished merely by throwing doors and windows wide open to let the wind blow into the house; the air conditions within the pen must be so controlled that weather has only a secondary effect.
