Book excerpt: Excerpt from Natural and Artificial Incubation and Brooding This bulletin has been prepared with the Idea of helping, If possible, those already in the poultry business, both large and small breeders, who have, perhaps, experienced some difficulty In the hatching or brooding branch of their work, and those without experience who intend starting to this branch of agriculture. The Essential of Successful Incubation. The most common cause of poor results or failure in incubation is the use of eggs of low vitality. Successful incubation begins long before the eggs are laid. The eggs must be from stock of high vitality that have never been forced; that are fed all the green food they will eat, and some form of animal food as well as grain. While fowls will sometimes lay a goodly number of eggs upon a grain diet, yet the eggs are oftentimes lacking in those food elements that the embryo requires, and they often hatch poorly, and those chicks that do hatch will be of impaired vitality, very difficult to raise. The vitality of the breeding stock, food or housing, and the range should be carefully looked after, as the neglect of any one of these factors will impair the vitality of the stock; consequently the eggs will not give good results with either incubator or hen. Vigorous Breeding Stock Necessary For Successful Incubation. The Male. Care should be exercised in the selection of the male, since his influence in the flock is so great. He should be fully matured and well developed, though not too heavy. Medium-sized male birds give good results when mated to hens of good proportions. That he be a sound bird constitutionally is of vital import. His head should give every evidence of masculinity, and should be of good size and of symmetrical proportions. A bright eye and a rather short, stout beak are other requisites. The body should present a symmetrical appearance, being filled out and carried well on stout legs of medium length, set well apart. In general, he should be active, a bird of quality, and one possessed of abundance of vitality and vigour. The Female. The above general characteristics may also be applied to the female. A two-year-old, a yearling hen, or a well-grown, well-developed, and fully-matured pullet may be used, but only when absolutely necessary. Many times the vigour of the flock has been greatly reduced by breeding from pullets. In some places where the raising of poultry is the main industry, the size of the fowls as well as the eggs has been reduced in just this way. Breeders are beginning to realize the necessity of breeding from fully matured, well-developed fowls if vitality, vigour, and prolificacy are to be maintained year after year. Indications as noted in the male will suffice to differentiate the desirable from the undesirable type. Generally speaking, about ten or fifteen females is considered a sufficient number for one male of the general-purpose breeds, such as Rocks, Wyandottes, Orpingtons, and Reds, and from fifteen to twenty for the Mediterranean breeds, as Leghorns and Anconas. The exact number of birds per male in either class depends greatly upon the vigour and constitution of the particular male bird used.
