To improve a breed or flock of poultry, use the eggs from the individuals hav- ing the desired characters. In breeding for increased egg-production, the number of eggs laid by a hen in a year is of far more importance than the color of the feathers. A hen lay- ing 200 or more eggs a year is worth many times more than one laying from 30 to 50. There are many poor layers in all flocks. By using trap-nests for a full-year test the Maine Experiment Station found that in a number of spring pullets all bred pure to type, only 3 laid more than 200 eggs; 10 laid 175 to 200; 11 laid 150 to 174, and so on down; 11 laid 75 to 100; 6 laid 50 to 75, and 5 laid 36 to 49. In the development of the breeds of poultry, much attention has been given to perpetuating the color and character of the feathers, combs, wattles, etc. In recent years, greater efforts have been made to strengthen the more important qualities, such as regularity and fre- quency of laying, early maturity and other qualities, depending on the kind of poultry. 313.
