The subject of turning eggs is another source of rather meaningless
controversy. Of course, the hen moves her eggs around and in doing
so turns them. Doubtless the reader, were he setting on a pile of
door knobs as big as his head, would do the same thing. As proof
that eggs need turning, we are referred to the fact that yolks stick
to the shell if the eggs are not turned. I have candled thousands of
eggs and have yet to see a yolk stuck to the shell unless the egg
contained foreign organism or was several months old. However, I
have seen hundreds of blood rings stuck to the shell. Whether the
chick died because the blood rings stuck or whether the blood rings
stuck because the chicken died I know not, but I have a strong
presumption that the latter explanation is correct, for I see no
reason if the live blood ring was in the habit of sticking to the
shell, why this would not occur in a few hours as well as in a few
days.
In the year 1901 I saw plenty of chicks hatched out in Kansas in egg
cases, kitchen cupboards and other places where regular turning was
entirely overlooked.
Mr. J.P. Collins, head of the Produce Department of Swift & Co.,
says that he was one time cruelly deserted in a Pullman smoker for
telling the same story. The statement is true, however, in spite of
Mr. Collins' unpleasant experience. Texas egg dealers frequently
find hatched chickens in cases of eggs.
Upon the subject of turning eggs the writer will admit that he is
doing what poultry writers as a class do on a great many occasions,
i.e.: expressing an opinion rather than giving the proven facts. In
incubation practice it is highly desirable to change the position of
eggs so that unevenness in temperature and evaporation will be
balanced. When doing this it is easier to turn the eggs than not to
turn them, and for this reason the writer has never gone to the
trouble of thoroughly investigating the matter. But it has been
abundantly proven that any particular pains in egg turning is a
waste of time.
Cooling Eggs.
The belief in the necessity of cooling eggs undoubtedly arose from
the effort to follow closely and blindly in the footsteps of the
hen. With this idea in mind the fact that the hen cooled her eggs
occasionally led us to discover a theory which proved such cooling
to be necessary. A more reasonable theory is that the hen cools the
eggs from necessity, not from choice. In some species of birds the
male relieves the female while the latter goes foraging.
But there is no need to argue the question. Eggs will hatch if
cooled according to custom, but that they will hatch as well or
better without the cooling is abundantly proven by the results in
Egyptian incubators where no cooling whatever is practiced.
