How do chickens lay eggs?
Chickens will lay eggs as long as they have been properly cared for.
The only exception is when a hen has been treated cruelly.
That, or if there is some sort of health issue with the chicken.
A healthy chicken should lay eggs every day once they reach maturity.
Most chickens stop laying eggs during the winter.
They will begin to lay eggs again in late March or early April.
This varies depending on the breed of chicken, its environment, and how cold it gets in your area.
A hen can lay anywhere between one and seven eggs each week.
However, if there are roosters present in your flock, she will only lay one egg a week.
This is because the roosters will fight with each other for dominance, and the stronger rooster will push away the weaker ones.
The weaker roosters do not have a chance to mate with any of the hens, so they do not pass on their genes to offspring.
What’s the Process of a Chicken’s Egg Development?
The egg itself is formed inside the chicken’s reproductive system.
The oviduct is a series of five chambers in which all egg formation takes place.
It usually takes between 20 and 26 hours for an egg to pass through these chambers before it is laid.
The first stage of egg development occurs in the infundibulum, where the yolk is released from the ovary.
The infundibulum starts to move the yolk down towards the magnum, where it remains until it is fertilized or becomes a blood spot.
In the second chamber, known as the uterus, membranes surround and protect the egg.
The actual egg white will surround the egg within the uterus.
The third part of the oviduct is known as the isthmus, where the inner and outer shell membranes are added around the egg white.
In the next part of this series, known as the vagina, calcium carbonate crystals begin to form – then later mineralize with more calcium-rich fluids – to create the shell.
The egg moves through this portion of the oviduct at a speed of about one centimeter per hour, which gives the shell time to form properly.
Finally, in the cloaca, the egg is coated with albumen (a watery protein).
It is then pushed out into the open when it is laid.
After an egg has been laid, the hen enters what is known as the ‘resting phase’.
This means that she will not mate with any roosters for about 25 hours.
If a male manages to mate with her during this period, then there is a chance that she will produce a double-yolked egg.
Reasons Why Hens Will Not Lay an Egg
There are several different reasons why a hen will not lay an egg.
For example, if she has become stressed or ill, then this can cause her to stop laying eggs for at least 24 hours.
If you suspect that your chicken is ill, it is highly recommended that you seek the advice of a vet.
This is because some illnesses can be transferred to humans, and eggs may also become contaminated with harmful bacteria.
As far as possible, try to identify any potential problems that might cause your chicken not to lay eggs.
Usually, the problem will be obvious – for example, if she has a broken leg or wing.
Make sure that she has access to food and water at all times, and try to keep her coop clean so that it is free from harmful bacteria.
