The ordinary young chicken weighs about i|- ounces (rather less than more) when twenty-four hours old. At three to four weeks it should weigh ^ pound ; at six to eight weeks, i pound; at nine to" eleven weeks, 2 pounds; at three months a chicken of the medium-weight breeds should weigh from 2^ to 3 pounds, the cockerels generally being the heavier birds, though the largest pullets will often outweigh the average cock- erels. From this time birds of this class should grow at the rate of about i pound a month (a little less for smaller speci- mens, a little more for larger ones) until from six to eight months old, when they should be full grown and of average weight for specimens of the kind, in fair flesh but not fat. In the smaller breeds the period of growth is a little shorter, but not so much as would be expected, considering the rapidity of early growth and the size of the birds at maturity. In the larger breeds growth is very rapid. The best- FiG. 316. Goslings nine weeks old growing specimens in all breeds are usually a little ahead of the others from the start. In Asiatics these specimens often begin, about the ninth or tenth week, to grow.
