Chalazae work alongside albumen layers to keep the egg yolk intact. They operate like yolk scaffolding, supporting and balancing the yolk's movements so that delicious, bright center stays, well, center. This is especially important for fertilized eggs.

What protects the egg yolk from breaking?
Vitelline Membrane: This is the covering of the yolk. Its strength protects the yolk from breaking. The vitelline membrane is weakest at the germinal disc and tends to become more fragile as the egg ages.
Why do my egg yolks break so easily?
The reason the egg yolks break up easily on contact with a pan or taking them out of the egg is because the hen has a lack of protein in her diet. That's it in an "eggshell". It could be low quality feed, molting or stress.
What happens if the yolk is broken?
The yolks and inner membranes become resilient and weak which is why they break down easily. However, it really doesn't matter if you eat such eggs. Since the broken yolk wouldn't harm you in any way. Although you can take care of the eggs so the yolk don't break off.
What holds the egg yolk together?
Opaque ropes of egg white, the chalazae hold the yolk in the center of the egg. Like little anchors, they attach the yolk's casing to the membrane lining the eggshell.
What is germinal disc?
The germinal disc, also called the blastodisc, is a small, circular, white spot (approximately 1.5-3 mm across) on the surface of the yellow yolk of a bird's egg.
Why do egg yolks stick?
In fresh eggs the albumen sticks to the inner shell membrane more strongly than it sticks to itself because of the more acidic environment of the egg. ... After the protective coat is washed off the egg shell the egg becomes porous and begins to absorb air and loose some carbon dioxide contained in the albumen.
Why do my eggs not peel well?
Why are fresh eggs so hard to peel? The fresher the eggs, the harder they are to peel. This is because the egg white or “albumen” in a fresh egg has a relatively low pH level, making it acidic. When cooked, these fresh egg whites bond strongly to the inner shell's membrane.
What does it mean when you crack open an egg and the yolk is runny?
You can also check to see if the whites or yolk of the egg are runny. This is an indication that the egg is old and that the quality has declined. But this does not necessarily mean it has gone bad, and it can still be perfectly fine to use (4).
Can you break a yolk by shaking an egg?
It is unlikely that simply shaking by hand will beat an egg. Eggs have inner anchors called chalazae that affix the yolk to the membrane. It is also cushioned by the membranes and an air pocket.
What does the germinal disc do in an egg?
Germinal disk (blastoderm) -- 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 embryo develops from this disk, and gradually sends blood vessels into the yolk to use it for nutrition as the embryo develops.
What does the egg membrane do?
Immediately beneath the shell are two membranes, the outer and inner shell membranes. These membranes protect the contents of the egg from bacteria and prevent moisture from leaving the egg too quickly.. Because the body temperature of a hen is approximately 106° F, eggs are very warm at the time they are laid.
What is the white squiggly thing in an egg?
The chalazae (plural) are rope-like structures made of protein that act as a support system for the yolk. It keeps the yolk suspended in the center of the egg and safe from pressing against the shell or settling on one side of the egg. When cracking an egg, there's really no need to remove the chalazae.
