How Do Chicken Eggs Get Fertilized?

This is a question that more than 2688 of our readers have been asking us! Luckily, we have found the most appropriate information for you!

There are a few common misconceptions about fertilized eggs that I hope to clear up in this article, but first, it is important to understand the differences between fertilized and unfertilized eggs as well as incubated and un-incubated fertilized eggs.

The hen’s genetic material, termed the blastodisc, can be identified on an egg yolk as a light-colored dot with irregular borders. The blastoderm will remain in a state of suspended animation, so to speak, forever unless warmed at particular temperatures for several hours. When a fertile egg is incubated under precise, steady temperatures and humidity levels for 21 days, the blastoderm may develop into a chick . Fertilized eggs have remnants of the male’s sperm and a small layer of cells that could form the embryo. FACT : Only eggs that are incubated and begin developing can be identified as fertilized after a minimum of 3 days. The only way to determine whether an unincubated egg is fertilized is to crack it open and identify the blastodisc or blastoderm.

How do farmers know if a chicken egg is fertilized?

If you want to know 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.

Are the eggs we eat fertilized?

Most eggs sold commercially in the grocery store are from poultry farms and have not been fertilized. … Given the right nutrients, hens will lay eggs with or without having been in the presence of a rooster. For an egg to become fertilized, a hen and rooster must mate prior to the formation and laying of the egg.

Can chickens fertilize their own eggs?

Any kind of egg bought in a supermarket will not be fertile.. Commercially produced eggs are laid by hens who are either in cages, barns or pastures – but without access to a male chicken. And without a male, a hen’s eggs cannot be fertilised.

Why do chickens lay unfertilized eggs?

Chickens lay unfertilized eggs because they are attempting to collect a clutch. In some cases, hens are bred to have long laying seasons so they might lay a couple hundred eggs in a single season. Breeds that have not been bred for laying might only lay a dozen eggs and only during a specific time of year.

Courtship, mating, and raising brood starts in the springtime. The increase in daylight energizes the hormones, and the increase in hormones leads to procreation behaviors.

However, if you want fertilized eggs, you will need a rooster to perform his duties with your hens, which he will be happy to do continuously. A rooster is genetically programmed to take the task of populating the world with his offspring, and he is single-minded about it, dedicated even! The pineal gland in the chicken’s brain detects the increase in light – this, in turn, stimulates the manufacture of androgen, estrogen, and progesterone – the hormones responsible for increasing egg production and broodiness. You should remember that many of today’s chicken breeds have had the innate ability to become broody bred out of them, so few, if any, will sit on eggs for you. Most of these ‘secondary’ brooders will not sit for 21 days, so placing eggs under them is probably a waste of time, but occasionally one will see it through! It’s a bit like a rooster tango – he will approach the hen from the side, dropping a wing near to the ground and do a little fancy footwork around her. A Nicely Combed / Wattled RoosterHe will start ‘tid-bitting’ in earnest once spring arrives. If it turns out to be nothing of interest to the hen, she will brush him off, so he must be on top form in several arenas of showmanship and ability to win her approval. If you are witnessing a mating for the first time, you can be forgiven for thinking it’s more akin to rape than ‘love,’ but fortunately, the hens don’t see it that way. A rooster can adequately cover up to around 15 hens, but in reality, he likely will have favorites that he will tend to more frequently. Once the hen has decided she will accept the rooster, she will squat down to the ground and spread her wings to steady herself. He will mount her from the back, grabbing her head feathers in his beak and treading her with his feet to find a stable spot on which he can balance. Her sides can be ripped by claws or long spurs, causing some skin to be torn up. Once he maneuvers into position, the hens’ cloaca averts as does his, resulting in a cloacal ‘kiss.’ His sperm is transferred from his papilla to the hens’ vagina, beginning its long journey. Male The rooster has two working testes which are located in his abdomen very near to the kidneys. Sperm from the rooster is deposited in the hens’ cloacal area and migrates up into the vagina, where it can rest in ‘pockets’ in the wall. Rooster sperm is viable for 7-10 days inside the pockets, although fresh is best. However, sperm intent on fertilizing travel on up into the area of the oviduct known as the infundibulum to ensure success. It takes about 5 hours for cell division to start, and at this point, it is called a blastoderm or embryo. If our hen is interested in being a mother, she will now find herself a nesting place that is quiet and dark. Firstly, make sure the rooster can’t hurt her during mating – trim spurs and talons; use a hen saddle if necessary. Secondly, when she is looking for a dark and secure place to set, try to encourage her into a small separate area where she can be undisturbed by the other birds. Our broody will diligently turn, warm, and fuss over her eggs for the next 21 days. They will learn all they need to know from her, and if the rooster is a ‘family guy,’ he, too, will take turns looking out for his offspring. The frenetic mating activity of spring and early summer will start to moderate when the days get too hot and humid.

This maybe an awkward thing for many to ask about but this bird question is asked so often! How does a rooster fertilize an egg? How do chickens become pregnant? Do hens have to mate in order to lay eggs? Dr. Jess explains it all below…

Chicken bird eggs come in many different shapes, sizes, and colors. Most of the eggs that you find at your neighborhood grocery store are either white or brown in color. The most commonly seen grocery store eggs are usually medium, large, or jumbo in size and have a ovoid shape to them. Female chickens do not need roosters around to mate with them in order to lay eggs. That’s why many chicken owners have only hens yet they still produce beautiful unfertilized eggs to eat. It all starts with a mating dance mostly performed by the flamboyant moves of the rooster. The rooster will circle the hen while moving his feet with his wings stretched down. It’s the rooster’s way of letting the female chicken know that it’s time to mate and that he is marking “his territory.” The hen will likely crouch and flatten her back for the rooster and hold still while he mounts her. He will likely bite down on the feathers of the hen’s head and neck for balance. The hen’s tail feathers will lift up and the rooster’s will be lowered so their vent or cloacas touch, called the “cloacal kiss.” It is the one entrance and exit hole through from which they urinate, defecate and transfer sperm. Unlike most mammals, a female chicken has only one rear hole that performs three important functions. The rooster’s cloaca has two functions, to pass feces and to transfer sperm to a hen. Instead, roosters have a small bump inside their cloaca called a papilla where the sperm are delivered to the hen. Once the sperm is in the hen’s body, it is held in the oviduct . A hen who was mated by a rooster can store sperm in her body and her eggs will be fertile for at least a couple of weeks and sometimes much longer before she needs to re-mate.

Spring Fever – Mating Season

Courtship, mating, and raising brood starts in the springtime. The increase in daylight energizes the hormones, and the increase in hormones leads to procreation behaviors.The pineal gland in the chicken’s brain detects the increase in light – this, in turn, stimulates the manufacture of androgen, estrogen, and progesterone – the hormones responsible for increasing egg production and broodiness.These hormones, in turn, produce a cascade of other hormones necessary for the development of the yolk and the soon-to-be embryo.You should remember that many of today’s chicken breeds have had the innate ability to become broody bred out of them, so few, if any, will sit on eggs for you. If you don’t have a broody hen, you will certainly need an incubator.An interesting thing to note here is that broodiness is ‘infectious.’ If you get one hen to go broody, you will likely have at least one more of the ladies who want to brood!Most of these ‘secondary’ brooders will not sit for 21 days, so placing eggs under them is probably a waste of time, but occasionally one will see it through!

Chicken Courtship

Some roosters are a little bit romantic – others not so much. To indicate interest in a particular hen, the rooster will perform the courtship dance.It’s a bit like a rooster tango – he will approach the hen from the side, dropping a wing near to the ground and do a little fancy footwork around her.This is his ‘come hither dance, and he will repeat it until she either indicates she likes him or walks away from him.Hens’ are no easy mark, though – they will have evaluated his merits as a suitor. Does he provide food? Is he a good protector? Is he healthy?And is he sexy? (a red comb and wattles really get the ladies interested). If he passes the inspection, she will let him mate. If not, she will ignore him.He will start ‘tid-bitting’ in earnest once spring arrives.He will pick up interesting morsels for the hen to inspect, luring her over to check it out.If it turns out to be nothing of interest to the hen, she will brush him off, so he must be on top form in several arenas of showmanship and ability to win her approval.Occasionally, a hen will dislike the rooster and may never mate with him at all, but this is rather unusual.Hens also have a neat little trick about rooster sperm.If they decide they don’t want the sperm from the mating, they can eject most sperm to avoid fertilization.

Mating

If you are witnessing a mating for the first time, you can be forgiven for thinking it’s more akin to rape than ‘love,’ but fortunately, the hens don’t see it that way.The act of mating looks quite barbaric but, in fact, rarely results in serious injuries.He can mate anywhere from 10-30 times per day depending on the level of co-operation from the ladies.A rooster can adequately cover up to around 15 hens, but in reality, he likely will have favorites that he will tend to more frequently.The optimum time for mating is early morning, when his sperm load can be anywhere betweenOnce the hen has decided she will accept the rooster, she will squat down to the ground and spread her wings to steady herself.He will mount her from the back, grabbing her head feathers in his beak and treading her with his feet to find a stable spot on which he can balance.He will use his claws to get a steady grip on her – this is where most injuries to hens occur. Her sides can be ripped by claws or long spurs, causing some skin to be torn up.You can help the hen to ensure that the roosters’ spurs are short and if he is frequently mating with certain hens, fit them out with a hen saddle for protection.

Chicken Reproductive Anatomy

The mating act is very brief. Once he maneuvers into position, the hens’ cloaca averts as does his, resulting in a cloacal ‘kiss.’His sperm is transferred from his papilla to the hens’ vagina, beginning its long journey.The mated hen will shake out her feathers and go about her business as if nothing happened – so much for love.

The Journey

Sperm from the rooster is deposited in the hens’ cloacal area and migrates up into the vagina, where it can rest in ‘pockets’ in the wall.Rooster sperm is viable for 7-10 days inside the pockets, although fresh is best.However, sperm intent on fertilizing travel on up into the area of the oviduct known as theThe hen’s oviduct is approximately 30 inches long, and the intrepid sperm travels about 29 inches to reach the infundibulum and deliver the genetic code to the germinal disc of the egg.Once the rooster DNA is delivered to the hen DNA in the germinal disc, they fuse and become a zygote (fertilized seed).It takes about 5 hours for cell division to start, and at this point, it is called a blastoderm or embryo.This includes laying down albumin, building the shell, and applying the bloom before the eggs lay.She will start to cache her eggs until she has enough to start incubating them.If she has too many, remove some to another hen or incubator.

Development & Brooding

If you allow the hens to hatch their own, you can do a few things to make the process smooth.Firstly, make sure the rooster can’t hurt her during mating – trim spurs and talons; use a hen saddle if necessary.Secondly, when she is looking for a dark and secure place to set, try to encourage her into a small separate area where she can be undisturbed by the other birds.Add in a feeder and waterer, so she has her own little ‘apartment,’ and she should be all set. The area should, of course, be fully secured and be locked down for safety overnight.Once our hen has decided she has enough eggs to sit on, she will start to brood. This means she will sit on those eggs for the next 21 days until they hatch or die.She will chase off the rooster if he tries to mate with her at this point.Once she becomes fully broody, the rooster will not fuss with her. He may be a Mr. Nice Guy and sit on her eggs for a while, but most roosters don’t. His involvement with the chicks will not start until they are hatched.Our broody will diligently turn, warm, and fuss over her eggs for the next 21 days. During that time, she will rarely leave the nest.You may see her once a day run out to poop, perhaps have a quick dust bath and then run back to the nest where she will rearrange her eggs before sitting again – total dedication!

Hatching

Once hatched, Mama will take great care of her little chicks. No one will mess with a broody hen and chicks – she will defend them most vigorously.They will learn all they need to know from her, and if the rooster is a ‘family guy,’ he, too, will take turns looking out for his offspring.Here is a complete guide on raising chicks once they have hatched.
