There are certain occasions when it i» necessary to use related birds in the breeding pens. In. the formation of a new breed or in the establishment of a new colour, one has no option but to in-breed, possibly to inbreed very closely, but whenever possible such a practice should be avoided. Consanguinity nearly always results ia the enfeeblement of the offspring—chickens of related parents are generally somewhat delicate, they are difficult to rear, and they rarely grow to so large a size With turkeys, more 'than any other class of poultry, inbreeding seems to hare been practised. I have no hesitation in saying that if healthy, fully-matured, and unrelated stock birds are used, and that if the conditions under which the birds live are favorable, there is very little more difficulty in rearing turkeys than there is in rearing other classes of poultry.
