Prof. Gowell, at the Maine Agricultural Station, carried on his breeding with Barred Plymouth Rocks, and it is interesting to note that his average for some eight years, taking his star performers, was 134.27 eggs per hen for twelve months, while at The Corning Egg Farm the flocks of fifteen hundred pullets averaged per hen, for ten months laying, 143.25 eggs in 1909, and 145.11 eggs in 1910. Here was a difference of two months in time, and yet the large flocks, taken as a whole, not weeding out a few star performers, surpassed the twelve months’ record of the Barred Plymouth Rocks at the Maine Station by almost nine eggs in 1909, and ten eggs in 1910. This significant fact made considerable impression on a number of breeders in the neighborhood of Boston, with the result that, in the last two years, The Corning Egg Farm has supplied a large number of hatching eggs and considerable breeding stock for farms in New England. As one gentleman from Boston pointed out, even with the difference in price between the brown and the white egg, he found that he could not really afford to continue with the breeds laying the brown egg, for the Leghorn, in numbers, more than made up for the slight difference in price between the two colors, in the Boston Market. And, as he still further pointed out, it took less food to supply the Leghorn than it did any of the larger breeds, and this, of course, was another source of economy. It should be remembered that the “Strain” of any breed is most important. One may purchase White Leghorns where the inbreeding has been so great that they are not capable of laying eggs in large numbers, and the percentage of fertility from the hatching standpoint in such birds will be a most uncertain quantity. Such chicks as may be hatched will be far from strong, and the mortality will run into figures which will dishearten anyone. Line Breeding--Not Inbreeding In the building up of a great strain of birds it is necessary to “line breed,” for, if the old theory of introducing new blood to prevent inbreeding, and the method of introducing the new blood, was, as is done in so many places even to-day, by introducing males from other sources, the entire system falls down. Nothing is accomplished and time is worse than wasted. The possibility of handing down the virtues of mother to daughter, and of father to son, is eliminated. If all the qualities of a given “Strain” are to be handed down line breeding must be adhered to in the strictest sense. Inbreeding, however, must be avoided, or disaster will follow.
