EFFECTS OF INBREEDING.
Take a flock of common hens, of all colours, shapes, and sizes, so as to conduct an experiment. Place with them a purebred Plymouth Rock cock; and the chicks will become uniform and so nearly like Plymouth Rocks that it will be difficult to distinguish them from purebred. To continue the experiment the next season use a cock of the last season's production, with pullets of the same blood. That is, keep one of the halfbred Plymouth Rocks and mate him with a few of the halfbred pullets. The result will be that chicks hatched from the eggs kid by the halfbred pullets, will revert to their granddams, and instead of being uniform, like the cross from the pur« Plymouth Rock, will come of all colours, shapes, and sizes (when larger). By inbreeding the uniformity is destroyed, because the parents are not purebred. Hence, always use a purebred male in the flock, no matter of what breed it may be; and your chicks will be not only uniform but superior to those of the previous season. The same rule applies to the breeding of cattle and sheep," and to all domestic animals.
