“The Cloacal Kiss”
During this “cloacal kiss” the hen must open up her cloaca so his sperm can reach the unborn/unlaid eggs in her oviduct. After he has passed his sperm they carry on their business as usual. The sperm that he passed will fertilize the eggs she had that day and some days after.

Why do chickens lay unfertilized eggs?
This is called candling the eggs. This step normally takes place during the 9th day of incubation. We use a Brinsea machine to candle the eggs. This allows you to pop the egg on the stand, cover it over with the lid and look through the eye piece to see if there is any fertilisation and development of the egg.
How do chicken lay eggs without fertilization?
The next question is perhaps, "Why do chickens lay unfertilized eggs at all?" The reason is that the egg is mostly developed before being fertilized. The chicken cannot know in advance whether the egg will end up fertilized or not, so it just has to go ahead and grow the egg in the hopes that it will be fertilized.
How are bird eggs fertilized?
Hens are able to lay eggs without mating through a process called parthenogenesis, also known as "virgin birth". Parthenogenesis is a form of asexual reproduction in which an egg develops into an embryo without being fertilized by a male sperm.
Is it safe to eat fertilized chicken eggs?
During mating, the male bird goes on top of the female, facing the same direction. They have an entrance called cloaca which they rub against each other. From the cloaca, the male sperm passes onto the female ova, where it is fertilized. After fertilization, the egg comes out of the female cloaca.
Are fertilized eggs healthier?
Fertilized eggs are fine to eat, in fact some people claim they healthier than unfertilized eggs, although we've never seen any data supporting that. (Let's be honest; if the fertile egg is fresh and unincubated, you're going to have the addition of just half a cell.)
Can a hen lay eggs without mating?
There is no nutritional difference in fertilized eggs and infertile eggs. Most eggs sold today are infertile; roosters are not housed with the laying hens. If the eggs are fertile and cell development is detected during the candling process, they are removed from commerce.
What happens if a hen sits on an unfertilized egg?
It's a common misconception that you need a rooster to encourage your hens to lay. The truth is that hens will lay eggs with or without a rooster. Without a rooster, your hens' eggs are infertile, so won't develop into chicks.
Can female chickens lay eggs without a male?
A domestic hen will go “broody” even if her eggs are unfertilized and she will sit on them for as long as she would if the eggs were fertilized. During that time, she won't lay any more eggs..so the farmer will take those eggs from her so she starts to lay again.
Can a chicken lay 2 eggs a day?
Hens do not need a rooster in order to create and lay eggs. All they need is a safe place, time, and a healthy diet with enough protein and calcium to form healthy eggs. Of course, any eggs laid by a hen where no rooster is present are going to be unfertilized, and therefore will never hatch.
Can you eat chicken eggs if you have a rooster?
Sometimes, hens skip a day or lay two eggs in a day. This can be due to various factors such as stress, illness, or even age.
Why do you need a rooster with hens?
A rooster will mate with most or all of the hens in the flock. Once you have fertilized eggs, all you need is a safe place for the hens to nest and you can have chicks in no time. Another positive is that you can eat fertilized eggs the same way you can eat unfertilized eggs.
How long is a bird pregnant before laying eggs?
The rooster is a protector.
A rooster doesn't just scout for food, he's got an eye out for predators alerting the flock to danger, pushing hens to safety and aggressively defending against attackers from the air or ground. Taking this responsibility seriously, a rooster may give its life in defense of the flock.
How do you know if an egg is fertilized?
Birds don't get pregnant. If you are asking how long from point of release from ovary of the ovum until the time the egg is laid, approximately 24 - 48 hours although this varies somewhat by species. How long does it take for a robin to hatch and leave the nest?
