it has a tiny dot from where the chicken/hen has layed there egg
That's the rooster sperm.
The tiny white dot connected to the yolk in an egg is called the chalaza. Its primary purpose is to anchor the yolk in the center of the egg white, helping to keep it stable and providing protection as the embryo develops. The chalaza also plays a role in maintaining the integrity of the yolk during movement, ensuring it remains suspended and nutritionally accessible.
It's called the germinal disc or blastodisc - a small, circular, white spot (2-3 mm across) on the surface of the yolk; it is where the sperm enters the egg. The nucleus of the egg is in the blastodisc.
The white dot on the yolk, known as the germinal disc or blastodisc, is where fertilization occurs in a fertilized egg. It contains the genetic material from the hen and, if fertilized, will develop into an embryo. In unfertilized eggs, this dot remains as a small marker on the yolk but does not develop into anything. Its presence indicates the egg's potential for development under the right conditions.
The primary natural purpose of egg white is to protect the yolk and provide additional nutrition for the growth of the embryo (when fertilized).
A fertilized bird egg looks exactly the same as any other egg. There's no way to tell from the outside. Inside the shell, however, it is possible to tell (although if you crack the egg open to see, you can't hatch it). All eggs have what's called a 'blastocyst' on the yolk which is just a tiny white dot. When an egg is fertilized the blastocyst turns into a blastoderm. It houses the fertile cells that will grow into a chick under proper conditions. In an unfertilized egg, the blastocyst (also called the germinal disc) is just a tiny white dot. However, in a fertilized egg, the tiny white dot changes to a larger round spot that often looks like a bullseye.
If The egg soaks in White Vinegar then the White vinegare will make the egg bounce the highest.
It means that the egg has been fertalized......and it is the start of a baby chic
If after 24 hrs the egg is not a white/opaque it probably is fertile.
The germinal spot is that small (2-3mm diameter) white dot on an egg yolk. If the egg has been fertilized, the germinal spot is where the baby chick will start to grow.
The weight of the tiny egg is 0.5 ounces.
The egg white provides a semi liquid equivalent of the human amniotic fluid environment for the growing chick. The embryo chick starts as a tiny speck attached to the yolk. The yolk is the protein that the embryo uses to grow.
