Hens can lay eggs without the presence of a rooster, and they’ll continue to produce the same amount whether a rooster is around or not. However, if you want fertilized eggs and the chance to hatch chicks, that’s when a rooster becomes necessary. If you’re only interested in collecting eggs, simply keeping your hens well-fed is enough.
That said, there are some benefits to having a rooster in your flock. If you’re setting up a backyard coop, you might want to think about adding a rooster to the mix. Let’s take a closer look at the role of roosters and the idea of non-fertilized chicken eggs.
To understand if hens need a rooster to lay eggs, it helps to know how eggs form inside a hen. A hen’s reproductive system includes an ovary and an oviduct. Although hens start with two ovaries, only one remains active as they mature.
This single ovary is responsible for producing eggs. The process takes about 24 to 48 hours. It starts with the yolk forming in the ovary, which then moves into the first part of the oviduct, known as the infundibulum.
If the hen has mated with a rooster, fertilization happens here when the rooster’s sperm meets the yolk. If there’s no rooster, the yolk continues developing on its own.
Next, the yolk moves to the oviduct and then to the magnum, where the egg white (albumen) forms over about three hours. The egg then reaches the isthmus, where both the inner and outer membranes develop around it.
Finally, the egg enters the uterus, where the shell forms and hardens over 18 to 24 hours. Once fully developed, the egg is pushed out through the hen’s vent and laid, completing the process. This means hens can lay eggs whether or not a rooster is around—the rooster is only needed if you want fertilized eggs for hatching chicks.

Can Hens Lay Eggs Without a Rooster?
Yes, hens can lay eggs without a rooster’s help. A rooster’s job is to fertilize the eggs, which is only necessary if you want to hatch chicks. If you have a rooster but are collecting eggs for eating, make sure to store them in a cool place to prevent any chance of fertilization.
Breeding chickens in your backyard is possible but can be tricky. Allowing your hens to hatch eggs means you’ll end up with more roosters, and while they can live together peacefully as young birds, they often start fighting as they grow older. If you need to manage the number of roosters, be sure to handle the situation as humanely as possible.
How Does A Rooster Fertilize An Egg?
A single rooster can fertilize the eggs of up to ten hens. To do this, he needs to mate with a hen so that his sperm reaches her oviduct, fertilizing the eggs she will lay in the coming days. If you’re looking to grow your flock, having a rooster around and allowing him to mate with your hens is essential.
Roosters become especially active in spring, when they begin their mating rituals to attract hens. They usually perform two main actions: “tidbitting,” where they cluck while picking up bits of food to share, and the “rooster dance,” a display to impress the hens.
What is a Tidbitting Rooster?
Tidbitting, often referred to as the “rooster dance,” is a behavior where a rooster makes excited clucking sounds while moving his head and neck in a rhythmic motion. He might also pick up bits of food and drop them to attract hens and encourage them to join him.
The actual mating process between a rooster and hen happens quickly. After tidbitting, the rooster will hop onto the hen’s back. If she’s willing, she’ll squat down and spread her wings. The rooster then balances himself and, when positioned correctly, lowers his tail to engage in what’s called a “cloacal kiss.”
Unlike many animals, roosters don’t have a phallus. Instead, they have a small bump called the papilla, which is where their sperm comes from. The hen extends her body to receive the sperm, allowing it to fertilize her eggs. The remaining sperm stays in special pockets to fertilize eggs over the next several days.
Once mating is done, the rooster moves on, and the hen goes about her day. Though a rooster’s sperm production may slow with age, he can remain active for many years.
How Long Will Chickens Lay Eggs Without a Rooster?
Hens don’t need a rooster to lay eggs. If a rooster is present, the eggs will be fertilized, but you can still eat them whether they’re fertilized or not. Fresh eggs collected daily are no different in taste or nutrients from unfertilized ones.
If you leave eggs in the nest for a day or two, it’s not always easy to tell if they’ve been fertilized or if a chick has started to develop, as you’d only notice by cracking them open. For those wanting to hatch chicks and expand their flock, you’ll need to allow the fertilized eggs about 21 days to incubate. The hen will sit on them during this time, or you can use an incubator to keep them warm if she doesn’t.
If you plan to eat fertilized eggs, collect them daily and store them in a cool place to prevent any development. Some hens naturally prefer sitting on their eggs more than others, which can encourage other hens to do the same.
To check if an egg is fertilized, you can use a method called candling, where you hold the egg up to a bright light to examine its contents. You might see signs of early embryo development, but this process takes a bit of practice to understand the differences. If you’re still unsure or want more details, consider reaching out to an expert or a friend who raises chickens.
