We always associate procreation with males and females, and while chickens work the same way, do hens need a rooster to lay eggs?
A female chicken, commonly referred to as a hen, can lay eggs without requiring a rooster to be present. Due to the absence of the male rooster, the eggs will be infertile and not have the ability to grow a baby chicken in them.
It all comes down to your preference and what you intend to do with your chickens.
If you’re looking to hatch a family of chicks, you will need a rooster to hang out with the hens.
However, if your goal is to sell eggs and have fresh farm eggs usable for eating and cooking, you won’t need a rooster present.
How Can a Hen Lay Eggs Without a Rooster?
Reproductive systems in hens consist of an ovary and oviduct.
In the hen’s reproductive system, one ovary typically ends up not working.
This is normal and is usually not anything to be concerned about.
In a healthy and still-thriving ovary, the egg is produced within 24 to 48 hours.
First, the yolk is made in the ovary.
It’s odd to think of, but yolks are chicken embryos.
From here, it is transferred into the infundibulum.
This is the first part of the oviduct.
If the hen has been mated to a rooster, this is where fertilization is birthed.
However, since we’re not talking about fertilization, we will skip over the sperm process.
The egg navigates further down the oviduct, where the egg white forms.
Following the development of the egg white, the egg travels farther down the oviduct.
Typically the time for this process to occur in about 3 hours.
The next procedure in egg production is where the membranes of the shells of the egg form.
This is located in the isthmus.
Within two hours, the shell membranes will be complete.
The final destination the egg travels to is the uterus.
It is kept in the uterus for up to 24 hours until the harder outer shell is created.
Then when the hen is ready, she will push the egg out the posterior orifice, also known as the cloaca.
Unlike mammals, which usually keep their eggs inside, chickens drop their eggs every day to increase the odds of fertilization and allow more baby chicks to be born.
Are Unfertilized Eggs Safe For Consumption?
It’s perfectly safe to consume unfertilized eggs as part of your daily nutrition.
Commercially sold eggs are always unfertilized (with rare exceptions).
Just be sure you properly cook the egg.
If you eat an egg not properly cooked, it can lead to sickness or infections like salmonella and other digestive illnesses.

Are Hens Happier With a Rooster Present?
Hens can live within a flock peacefully for many years without a rooster.
Some chicken owners do say a rooster will help the hens feel safer.
After all, a big part of his job is watching out for the flock.
But the reality is a bit more mixed.
One hen will take on an alpha role in all-hen flocks and may become a bit of a bossy chicken in the flock.
She may even develop physical characteristics like an aggressive rooster (though she won’t make a full sex change).
If you are going to keep a flock of hens without a rooster, be certain you look out for signs that one may be beating up the others.
One of the birds has to be on the top of the social hierarchy, and they aren’t always the nicest.
Examples of this may include:
- Scratches on the other hens
- Blood on the hay or in the cages
- The flock of hens straying away from one hen when she is present
If this happens, consider rehoming one or a few of the hens to prevent another incident.
Why Does a Hen Lay Eggs Without a Rooster?
Despite common misconceptions, hens do not require a rooster to produce eggs.
The egg-laying process is a normal part of the hen’s reproductive system, whether birthing a baby chicken or producing eggs for consumption.
Interesting fact: If unfertilized eggs are left in the coop, some hens may eat them to recover the protein and nutrients they lost in making the egg.
While this practice is a bit split on opinion on the farming front, some owners feed their hens an occasional egg.

How Long Will Chickens Lay Eggs Without a Rooster?
Chickens can lay eggs without a rooster once they turn 6 months.
Please keep in mind this does depend on the breeds of chickens.
Hens in perfect health typically lay one egg per day in summer and much less in winter.
Troublesome Signs Affecting Your Chicken’s Egg Production
If you are having trouble getting eggs from your hen, they may not be producing them. Below are signs you need to watch for:
- Lethargy– a sick hen may sleep a lot and move around very little.
- Changes in color– in breeds with vibrant yellow-colored beaks and legs, a sickly hen will produce pale-ish yellow beaks and legs.
- Grimy Appearance– a hen with cracked feathers, missing many feathers, or balding are all tell-tale signs your hen is sick.
If you notice your hen is sick or unwell, please contact your local veterinarian immediately.
How Many Years Does a Hen Lay Eggs?
In a backyard flock, hens live for 6-8 years.
It is important to bear in mind the time of year it is.
The summertime plays a significant role in the egg production of your hen.
The more light there is in a day, the more productive your hen will be.
If you intend to produce eggs in the fall, spring, or winter, make sure you produce artificial light for 14-16 hours a day using a lamp with a 60-watt lightbulb.
