Poultry by Hugh Piper


Known as the Gallus giganteus of Temminck






By careful study of the characteristics of the various breeds, breeding from select specimens, and judicious crossing, great size may be attained, maturity early developed, facility in putting on flesh encouraged, hardiness of constitution and strength gained, and the inclination to sit or the faculty of laying increased.

Sir John Sebright, speaking of breeding cattle, says: "Animals may be said to be improved when any desired quality has been increased by art beyond what that quality was in the same breed in a state of nature. The swiftness of the racehorse, the propensity to fatten in cattle, and to produce fine wool in sheep, are improvements which have been made in particular varieties in the species to which these animals belong. What has been produced by art must be continued by the same means, for the most improved breeds will soon return to a state of nature, or perhaps defects will arise which did not exist when the breed was in its natural state, unless the greatest attention is paid to the selection of the individuals who are to breed together."

The exact origin of the common domestic fowl and its numerous varieties is unknown. It is doubtless derived from one or more of the wild or jungle fowls of India. Some naturalists are of opinion that it is derived from the common jungle fowl known as the _Gallus Bankiva_ of Temminck, or _Gallus Ferrugineus_ of Gmelin, which very closely resembles the variety known as Black-breasted Red Game, except that the tail of the cock is more depressed; while others consider it to have been produced by the crossing of that species with one or more others, as the Malay gigantic fowl, known as the _Gallus giganteus_ of Temminck, Sonnerat's Jungle Fowl, _Gallus sonneratii_, and probably some other species. At what period or by what people it was reclaimed is not known, but it was probably first domesticated in India. The writers of antiquity speak of it as a bird long domesticated and widely spread in their days. Very likely there are many species unknown to us in Sumatra, Java, and the rich woods of Borneo.

The process by which the various breeds have been produced "is simple and easily understood," says Mr. Wright. "Even in the wild state the original breed will show some amount of variation in colour, form, and size; whilst in domestication the tendency to change, as every one knows, is very much increased. By breeding from birds which show any marked feature, stock is obtained of which a portion will possess that feature in an _increased degree_; and by again selecting the best specimens, the special points sought may be developed to almost any degree required. A good example of such a process of development may be seen in the 'white face' so conspicuous in the Spanish breed. White ears will be observed occasionally in all fowls; even in such breeds as Cochins or Brahmas, where white ear-lobes are considered almost fatal blemishes; they continually occur, and by selecting only white-eared specimens to breed from, they might be speedily fixed
