Show EGGS FOR INCUBATION Uniformity in Size and Shape Is of Utmost Importance. Smooth Shells, All White or Brown Are Also Desirable No Way of Determining Fertility of Egg Nor Sex of Chick. Eggs for incubation, either natural or artificial, should be uniform in size, with smooth shells of good texture, tex-ture, according to N. L. Harris, superintendent super-intendent of the Kansas State Agricultural Agricul-tural college poultry farm. Irregularly shaped eggs will hatch nearly as well as smooth-shelled eggs, believes Mr. Harris. It is not considered consid-ered good practice, however, to set tha irregularly shaped eggs as there Is a possibility that pullets hatched from them will inherit the undesirable characteristic char-acteristic of producing poorly shaped eggs. As a rule it is not wise to place both white and brown eggs in the same Incubator, In-cubator, as the white eggs have a tendency ten-dency to hatch one or two days sooner than those with brown shells. There is nothing in the color of the shell which affects the time of hatching, but the small, quick maturing birds nearly all lay white-shelled eggs. The embryo em-bryo chicks of these breeds will develop de-velop more rapidly than those of the heavier breeds. Eggs that vary greatly in size should never be set in an incubator as the large eggs seem to receive more heat due to projecting higher in the machine than the smaller ones. Eggs with shells of poor texture which appear porous, allow the moisture to evaporate evapo-rate too readily and seldom, if ever, hatch. There is absolutely no way of determining de-termining the fertility of an egg previous pre-vious to Incubation, nor is there anything any-thing in the shape of the egg which will indicate the sex of the chick. |
