Life Cycle of Chicken

Introduction

Hens may survive for 8 to 10 years, and the majority of flocks will lay eggs for three years. Each year, there is a decline in egg production, egg shape, and shell condition. Most advertising layers are managed to keep for approximately two to three years because, after that, their egg production starts to decline. Owners should plan to retire elderly hens and introduce young hens every three to four years to maintain a small flock production.

Important Features

A domesticated subspecies of the untamed red junglefowl, the chicken is a bird that belongs to the Phasianidae family and is formally known as Gallus gallus. Farm animals, in this case, fowl, have a long-lasting intergenerational link and are reliant on the provision of resources, attention, and breeding from earlier generations. With a population of 215 billion as of 2018, chickens are thought to be the most prevalent domesticated animal. Its old paternal biological roots originated in India and later spread all over the world.

Life Cycle of Chicken

Chickens go through some significant changes throughout time, even though certain creature life cycles are much more spectacular than others. It's crucial to comprehend these modifications if you're a novice chicken owner so that you can provide your chickens the finest care possible throughout their life cycle.

Stage 1: Egg

• A hen must first pair with a Rooster to fertilize a batch of fertilized eggs. The next step is for the hen to develop an egg, which requires about 24 hours in total.

• The egg yolk, which is formed by the hen's ovary during the ovulation process and is at this point referred to as the oocyte, will form first in this process. The cockerel sperm will fertilize it internally as it descends the oviduct.

• Several layers of the egg white, or egg yolk, as well as a white membrane, known as the vitelline membrane, cover it as it continues to move down the oviduct. The egg white and yolk's covering will start to form as it continues to go through the oviduct. The egg will ultimately have a fully formed shell, at which point it is fully developed.

Stage 2: The Chicken

• The hen turns into a crabby hen once she has produced enough eggs. To maintain the ideal temperature for the eggs to hatch, a flock hen is an immobile bird that squats or sits on her eggs.

• All of the egg's nutrients are absorbed by the developing embryo. The embryo grows during this time, but only after three weeks, little chicks emerge. Although these chicks are still damp, they will have fully developed feathers in 4 weeks.

• The newly born chicks forms attachment to the doting mother at this point. Chicks are very reliant on their mothers during this time, following them practically everywhere.

Stage 3: Pullet

• The chickens are not particularly attractive at this stage. They resemble their extinct ancestors, the reptiles, in that they are extremely slender and all of their legs appear to be out of proportion when compared to adult chickens.

• You will notice severe harassment among them during this period because, as we all know, the hierarchy will be harsh. The young rapidly learn to get out of the way, but occasionally an older bird may choose to act like a complete jerk in front of the newcomers and will go to great lengths to annoy them.

• The young ones should be allowed to mix with the adults so they only have to experience the pecking order once.

• To prevent ongoing violence between the old and new, these chickens will be forced to learn their position in the flock.

• Once they are comfortable in their spot in the hierarchy, the roosters will start crowing whenever they have the chance.

• Around 17 weeks, the teenage hens will start laying eggs, however, this depends greatly on the species.

• Although some people refer to a female's initial eggs as "broody hen eggs" because they are so much less than hen eggs, a female is considered an adult after she has laid her initial egg.

Stage 4: Adult

• At this stage, male chicks develop into roosters, while female chicks develop into hens.

• The hen produces eggs after 6 weeks, and the chooks produce gametes. In ideal circumstances, a female hen will begin to produce eggs after 72-73 months at least, although this depends on when she goes through her initial molt.

• Every year, adult hens molt, losing their old feathers and growing new ones. After a year of routine egg laying, the chicken becomes worn out and begins to lay eggs erratically.

Conclusion

Under ideal circumstances, chickens that are unrestricted fowl can live up to 6–11 years. Poultry chickens can live a maximum of 30 years. Before being killed for their flesh by their owner, they can act as egg warmers for roughly a year to three years. Adult male roosters are exploited for sporting events like animal fighting. To make them become food birds, they are also castrated.

FAQs

Q1. How long can a chicken go without eating?

Ans. They nevertheless require frequent food, just like any other caged animal, to survive and grow. A chicken can typically only survive without its proper meal for 4–5 days before becoming severely undernourished.

Q2. Can relatives of chickens mate together?

Ans. Yes, you can breed chickens with relatives. It is a standard practice to breed relatives together to improve a particular trait in chickens. This covers breeding chickens that came from the same hatchery.

Q3. Do hens require illumination at night?

Ans. During darkness, chickens do not even require light. To have an excellent night's sleep, they need a minimum of six to eight hours of complete darkness. This rest period is essential for the health and wellness of the chicken; just as 13 to 14 hours a day of sunlight or artificial light are necessary for egg production.

Q4. Do hens perform well in the cold weather?

Ans. Chickens are very well able to withstand even the harshest cold weather. The birds' feathers provide superior protection, and they may be flared to produce an even cozier cloak. To keep those exposed portions warm, they may even tuck their beak or feet into soft feathers.
