A chick is born after 22 days of proper hatching and favorable incubation conditions.These 22 days after the reproductive process are divided in such a way that one day they spend in the oviduct and 21 days are for the incubation period for a chicken to develop. Before the egg is laid, a chicken embryo begins its existence within the hen.When the egg is laid, some embryonic developments take place and it usually stops until favorable conditions are established for incubation to resume. At first, all the cells look the same, but as the embryo develops, cell distinctions emerge. After 22 days, the chick appears upon freeing itself from the shell. A few hours later, the chick is now dry and the egg tooth will dry and fall off. The yolk of an egg is referred to as the ‘yellow component.’ The section of the egg where the newborn chick develops is this. While the infant chick is growing in the shell, the yolk supplies nourishment. The legs and neck develop later than the head and beak in the embryo. The wings develop inside the egg as well. The life of the embryo begins by incubation and the wing growth also takes place in chicks before they hatch. After the incubation, the egg membrane of the chicks, where the embryo’s life begins before hatching, during the last hours, the chick starts to knock on the air cell where it gets space with its beak as it wants to come out.You can also read about chicken facts and chickens losing feathers.What happens in the first two weeks of development inside a fertilized chicken egg?The fertilized embryonic disc resembles a ring, with a lighter-colored core portion that houses the embryo. To begin life in the egg, incubation is very important and hence mother hen plays the role of the first natural incubator. The eggs can survive without heat for 10 days before it needs to be incubated.The development of the germinal disc begins at first. The blastodermal stage is reached by the germinal disc. The segmentation cavity, located underneath the region Pellucida, takes on the appearance of a dark ring. There are two chalazae anchoring each yolk. On the yolk surface of the egg, you can see a Germinal disc which is small and circular. The blastodisc contains the nucleus of the egg. Inner shell membrane - the thin membrane located between the outer shell membrane and the albumin, the germinal disc appears in the vitelline membrane which starts the development of tissues, and blood circulation starts in the blastoderm. Tissue development and blood circulation begin. On day three of embryo development, the heart begins to beat and blood vessels can be seen, indicating that the embryo is making good progress since veins and blood vessels are visible and continue to grow and spread as the yolk sac develops. The yolk sac also provides food material to the embryo, the amnion shields the embryo by encircling it, and the allantois serves as a breathing organ that receives minerals from the shell. Within the shell, they are transitory organs and functions. By day five, a chick’s elbows and knees have formed, and the chick’s eyes may be seen. By day six of embryo development, the beak begins to form, and the chick begins voluntary movement in the shell. The beak, which is under the right wing, points to the air cell, and the egg white is entirely resorbed, and the comb begins to grow. By day eight, feather follicles have formed, ear canals have opened, claws have formed, and the embryo resembles a bird. Teeth and claws are produced on day 10. By day 12, feathers begin to form and are evident on the chick’s body, leg scales begin to appear, and there is a faint layer of feathers over the chick’s body. By day 14, the head has shifted to the pip position. The neck and legs develop later in the process. After the incubation, the egg membrane of the chicks, where the embryo’s life begins before hatching, during the last hours, the chick starts to knock on the air cell where it gets space with its beak as it wants to come out.What happens in the egg of a chicken during development?The development of the chick begins in the single-cell formed by the union of two parental cells, egg and sperm, and this first process of the growing system is known as fertilization. After the egg is laid, cooling of the egg starts but does not result in the death of the embryo as in a few minutes the hen comes to sit on the egg to incubate it. The fertilized embryonic disc looks like a ring. To begin life in the egg, incubation is very important and hence the mother hen plays the role of the natural incubator.The yolk of the egg is what we call the yellow part that plays a vital role in developing the embryo’s capacity. The egg cell, or germinal disc, is a tiny white speck on the yolk. This is the section of the egg where the newborn chick develops. The yolk feeds the infant chick while it grows in the shell and aids in the development of the embryo with the fertilized blastodisc, now known as blastoderm, which eventually becomes the embryo. The shell protects the egg and is covered in small holes which let the water pass out and air enter. The yolk is surrounded by thick and thin layers.Most of us do not know that the eggs we eat do not have embryos, as when the egg is laid it stays in suspended animation and the embryo couldn’t develop. Even the chicken eggs from the farm and from our backyard have not developed enough to be at the stage where one should think they are eating baby chick.How do you tell if your egg has a chick in it?If the egg is fertile, you should notice a black area in the center of the egg, with spider-like veins forming around it. If it isn’t, you should only be able to see the shape of the golden yolk inside the egg, with no evidence of an embryo or veins. If the egg is fertile, you will observe a very small white spot on the top of the yolk when we crack it. This is known as the germinal disc because it is here that embryo development begins. This is what indicates whether or not the egg has been fertilized. A single female cell and a single sperm from the male combine to make this disc.If your egg has been fertilized, crack it and look for the blastoderm, a white spot on the yolk, or maybe even blood spots. Fertilized eggs will have dark splotches in them, or might be entirely opaque, depending on the stage of development of the chick.Candling is a method used by poultry producers to determine whether their chickens’ eggs are viable and will hatch into baby chicks. The candling procedure illuminates the interior of an eggshell, allowing you to see what’s inside. Internally, the chick pips and repositions itself within the eggshell in the days leading up to hatching, so your eggs may move around. The chicks inside the shell move about and position themselves for hatching, causing the eggs to roll around a little. Before putting the eggs back into the incubator, light a candle for each one. Eggs that have shown no signs of development should be removed at this point. This is an example of an egg that is clearly not going to develop.When can you see development in a chicken egg?After your chicken lays an egg, you can either remove it from the chicken and eat it, or you can incubate it until it fully develops into a healthy baby chick. It takes a chicken around 24 hours to produce an egg inside her body, and another 21 days for the egg to hatch after it is laid. The process of fertilization is the first stage that takes place during the developing system or growth. The food need of a baby chick is different than its adult form.A hen does nothing to care for the eggs other than hiding them in a secure place until she is ready to sit on them. She will continue to lay eggs in this clutch until she has enough which is a number anywhere from 7-20. The hen starts to incubate the eggs if they were not taken by humans for eating or selling.From about day four or five in a properly developing egg, you’ll start to see a tiny spider-like marking appearing in the yolk area when you candle your eggs. This is the easiest way to see in white or light-colored eggs. As the third week starts, the chick starts to consume egg white and the chick is completely feathered, and the chick’s head is between its legs, and by day 18 chick’s becomes fully grown with their wings and beaks fully developed. The yolk sac is outside the body and the head is under the right wing. By day 19, the yolk sac moving into the body and embryo now occupies all the space except the air cell and the chick absorbed the yolk sac and umbilicus now closed the embryo and starts to breathe air. On day 21, the chick starts to knock on the air cell with its beak as it wants to come out of the air cell. For a baby chick, it is a heavy job when it breaks open the shell. The chick gets so tired of the labor that it just lay on the floor for a few hours. After that, the mother hen comes to the hatched chicken and in a few minutes, it becomes dry and active. In seven to eight weeks it becomes a chicken in a system for the first time. The leg development takes place a little late. If the egg does not hatch within 21 days, give them some more time. Sometimes it may take 26 days for the chick to come out.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
