Chicken eggs are not soft when they're laid. The shells are already hard when they come out. Shell material is secreted inside the oviduct as the egg passes along on it way to being laid. It's deposited around the egg and hardens before the egg is laid. Also question is, how long does it take for an egg shell to harden?
about 20 hours
One may also ask, how eggs are laid? Once stimulated, this gland triggers a process that leads to the release of an egg, or oocyte, from the hen's ovary. An egg can still be laid whether or not it has been fertilised by a male, but only fertilised eggs can develop into chicks. The orifice through which the egg leaves the hen is called the vent.
Moreover, what makes egg shells hard?
Calcium and vitamin D3 are two of the more important nutrients needed to build strong shells. “Calcium is the most important nutrient for eggshell development, and vitamin D3 is vital to getting the calcium where it needs to go,” says Biggs.
Is laying an egg painful?
Egg laying may be painful for young chickens. It certainly appears to be, at the very least, uncomfortable for some of them. As they strain to push the egg out, they make a wheezy, gasping sort of noise that sounds like an expression of discomfort.

There are three main causes for the production of soft-shelled or shell-less eggs. The first is that there may be a lack of calcium in your hen's diet. Hens require a lot of calcium to form each egg shell. You can add more calcium to your flock's diet by adding crushed oyster shells to their feed. Why has my hen laid an egg without shell?
Predators: Hens' bodies form their eggs while they sleep. If for some reason, they are startled in the night from a predator' visit, sometimes eggs can be laid without shells. Stress: Anytime the flock is under stress such as molting, predators, excessive temperatures, change in the flock etc. What does vinegar do to an egg?
If you soak this egg shell in vinegar (which is about 4% acetic acid), you start a chemical reaction that dissolves the calcium carbonate shell. The acetic acid reacts with the calcium carbonate in the egg shell and releases carbon dioxide gas that you see as bubbles on the shell. What came first the chicken or the egg?
So in a nutshell (or an eggshell, if you like), two birds that weren't really chickens created a chicken egg, and hence, we have an answer: The egg came first, and then it hatched a chicken. What animals lay leathery eggs?
Most lizard and snake species lay leathery eggs as well, although some snakes give live birth or carry the eggs inside their bodies until the eggs hatch. The leathery exterior helps hold in moisture and protect the babies while remaining slightly flexible. How do you break an egg hard?

The egg is strongest at the top and the bottom (or at the highest point of the arch). That's why the egg doesn't break when you add pressure to both ends. The curved form of the shell also distributes pressure evenly all over the shell rather than concentrating it at any one point. How do you strengthen egg shells?
Shell quality can be improved by providing the nutrients needed for the hen to build her bone reserves of calcium and make good shells: Feed a third to half of the calcium as large particles that are approximately ½ cm in size. What are eggs shells made of?
Eggshell is made almost entirely of calcium carbonate (CaCO3) crystals. It is a semipermeable membrane, which means that air and moisture can pass through its pores. The shell also has a thin outermost coating called the bloom or cuticle that helps keep out bacteria and dust. Do all eggs have hard shells?
Fish and amphibians generally lay eggs which are surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Eggs laid by snakes generally have leathery shells which often adhere to one another. Depending on the species, turtles and tortoises lay hard or soft eggs. Are thicker eggshells better?
Flock Management : Egg Production D. Strong shells matter because they impact egg safety. Strong eggshells are better able to keep bacteria out. One way to help keep eggs safe is by feeding hens a layer feed that includes Oyster Strong® System for shell strength. Why do eggs have shells?

To avoid the risk of food poisoning, make sure to boil eggs before eating their shell ( 18 , 19 ). Do chickens poop and lay eggs from the same hole?
The egg, poop and urine (which for a chicken isn't a liquid) exits out of the same hole (aka, the vent, as you can see above). BUT, when an egg comes out, the chicken's Cloaca is turned inside out so that the egg cannot come in contact with the intestines (fecal matter nastiness). Do Roosters have penises?
Do Roosters Have a Penis? Like the males of 97 percent of all bird species, a rooster does not have a penis. Can humans lay eggs?
Egg laying is a reproductive method that our lineage (mammals) moved away from (mostly) at least a hundred million years ago. To be clear, some species of mammals, called monotremes, do still lay eggs. Humans simply come simply from the primate lineage of placental mammals that are one of those strategies. Is my chick a rooster?
It's difficult for the average person to determine the gender (otherwise known as sexing) of a young chick. In most cases, even experienced chicken owners will not be able to tell whether they have cockerels or pullets until the chicks are least 2-3 months of age, often longer for some breeds like Silkies. How do chickens get pregnant?
As with most bird species, roosters and hens don't have external genitalia. Instead both partners procreate using an external orifice called a cloaca. When the cloacae are touched together, sperm is transferred into the female reproductive tract. Can male chickens lay eggs?
So do male chickens lay eggs? The answer is no; male chickens (roosters) do not lay eggs. Only female chickens (hens) lay eggs. Inside the developing ovary of every hen are hundreds of potential eggs, an organ in which male chickens do not possess. Do chickens pee?
In contrast birds have no need for a urethra since they don't urinate. Instead they coat their feces with uric acid that exits their body through the cloaca as moist chicken poop. Not producing liquid urine allows birds to have lighter bodies than mammals of similar size. A chicken's cloaca is an amazing organ. Are chicken eggs fertilized?
Edible egg advocates even say it never happens. Hens do not need a rooster to lay an egg; they do so (almost daily) on their own simply according to light patterns. However, if a rooster does mate with a hen, the eggs she produces are fertilized and, under the right incubation conditions, can bear chicks. How does a rooster fertilize an egg?
For the eggs to be fertilized, the hen and rooster must mate first, and this process must occur prior to the formation of the egg. Thus, if the hen has mated and she lays an egg, then that egg is fertilized. If the hen has not mated and she lays an egg, then that egg is unfertilized. Do chickens get sad when you take their eggs?
No, chickens do not feel any emotions at all when their eggs are taken, in a flock that lays eggs regularly and where the eggs are collected daily. The only time a hen would feel any kind of connection with the eggs is if she is “broody,” that is, ready to sit on a nest of eggs and hatch them. Do chickens have periods?
Chicken menstruation But think about it: female chickens have a menstrual cycle, during which a hen's ovary sends a yolk on its path.

Is laying an egg considered giving birth?
It is not only mammals that give birth. Some reptiles, amphibians, fish and invertebrates carry their developing young inside them. Some of these are ovoviviparous, with the eggs being hatched inside the mother's body, and others are viviparous, with the embryo developing inside her body, as in the case of mammals. Do chickens feel pain when killed?
