What will happen if the cords in the egg broke?

Answer 1

What you are referring to is chalaza. Ropey strands of egg white which anchor the yolk in place, in the center of the thick white (albumen). They are neither imperfections, beginning embryos nor are they rooster sperm. If by chance one or both of these cords breaks then the chances of the embryo inside the egg actually forming and surviving to hatch would be in question. The forming chick inside the shell must have room to form and if the chalaza did not hold it up it would drop the embryo to the bottom of the shell and possibly cause deformities.
