The effect of the individuality of the bird upon such egg quality points as weight of egg, shape of egg, and color of egg shell has been reported upon several occasions, one of the most noteworthy being the study made by Dr. Benjamin 1 at Cornell. All of the studies bear out his conclusion that these factors are very largely influenced by the natural tendency of the fowl.

One bird in the group consistently produced a light yolk, however, even though she did consume relatively large amounts of green food. The study reported herein was made primarily for the purpose of determining the effect of individuality upon the texture of the shell and the firmness of the white, . . . |
