How Many Eggs can a Chicken Lay in One Day?

A hen will typically lay only one egg per day.
A hen will typically lay only one egg per day.

When a hen reaches 18 to 20 weeks of age, she begins to lay eggs. In ideal conditions, she will generally produce about one per day, but may occasionally release two in the same 24-hour period. In a natural environment, the bird will continue to lay until she has several in the nest, at which point she will sit on them until they hatch. In a farm, however, the eggs are removed, and she will continue laying. During the course of her lifetime, a hen may produce as much as thirty times her body weight in eggs; at one per day, for almost two and a half years, that is about 900.

The Reproductive Cycle

The reproductive cycle is set by day length and generally lasts about twenty-four hours during the summer months. As the days shorten, and winter approaches, a hen will lay fewer eggs, skipping some days. Some will stop laying altogether until the spring arrives. The reason behind this is that winter is a bad time to raise chicks as the cold weather decreases their chances of survival.

A hen does not need to be fertilized to lay an egg, and most birds in a laying facility have never even been in contact with a rooster. The egg-laying passage, or oviduct, opens into the cloaca, the passage through which droppings and urine are expelled; however, during laying a flap of skin stretches down to separate these areas so that the eggs are not contaminated by droppings. For this reason, the newly laid egg is clean, although it can pick up dirt later, for example, from the hen’s feet.

After laying, the hen will leave the nest, allowing the egg to cool. This prevents it from hatching, but the embryo remains viable for up to two weeks in these conditions. The bird will continue laying each day until she has several eggs in her nest, at which point she becomes “broody.” A broody hen will sit on her nest all day and night, her wings spread slightly to help keep the eggs warm. Since the embryos’ growth was paused while the nest was being laid, they will all develop at the same time.

A broody hen will leave the nest, briefly, once a day to defecate, eat, and drink, and anyone who gets too close to her eggs will be pecked at. After three weeks of brooding, her chicks will emerge. Any that don not hatch will be left behind as she brings the new chicks out into the world for the first time, and the nest will be abandoned.

Maximizing Production

In farms or egg-producing facilities, this natural process is broken up. Lighting can be adjusted to make the hen think that the day length has not changed, so that production continues at summer rates throughout the year. Eggs are removed after they are laid, leading the bird to think that there are still not enough in her nest, and causing her to continue laying. A hen that is resistant to laying in a nest can be encouraged to do so by placing a few fake eggs there.

After several months of laying, a hen may go through a molting cycle, during which old feathers are shed and new ones grown. Due to the energy required to molt, the hen’s body will not have the resources to produce eggs. After molting, however, production tends to reach a new peak. When birds in a modern facility have been laying for some time, production is reduced and the quality of the eggs declines, and because of this, many facilities will use various methods to induce molting, in order to improve production and quality after the molt. One controversial method is by withholding feed for 7-14 days; however, this is not allowed in some countries, and an alternative method is changing to lower density food.

Factors Affecting Laying

Hens will normally continue to lay until they reach two or three years of age, but there are a number of reasons, apart from lighting, molting and age, that can reduce or stop egg production. One of these is poor nutrition. If a hen is not receiving proper amounts of feed, or if there is an imbalance, for example too much or too little salt, she will be unable to produce eggs. The bird must receive adequate amounts of vitamins, and minerals such as sodium and calcium.

If feed is not stored properly, molds can grow on it. These can release toxins that affect the health of hens and may prevent laying. Birds raised in backyards may also eat objects that are not part of their feed, and may be harmful, such as the seeds of toxic plants. External parasites — such as fleas, lice and mites — and external parasites — such as roundworms and tapeworms — may affect laying. A drop in egg production can also be caused by various diseases, and by stress.

We have a small chicken named Speckles. She is four or five months old. When will she start laying?


Has anyone ever heard of chickens laying coloured eggs?

How about purple, for example? Is this a dietary consideration, breed dependent or in fact a total fallacy?


I have 15 hens total. Nine are four years old and six are two years old. Today they produced 22 eggs. That's 22 eggs in 24 hours from 15 hens. They have done this often although my usual daily egg count is 14. So yes, they can and do produce more than one egg a day if they are well cared for. I typically get eight eggs per day in the winter.


How long can I keep chicken eggs in the refrigerator until they spoil?


Is there an artificial fertilisation for chickens?


How many days is an egg good if it's non fertilized and the hen is sitting on them?


I have chickens at and one has started to act strange. It goes off to be on its own. Could it be it's going to start laying eggs?


I have a duck and she lays one egg a day. She has 11 eggs and I removed the eggs every day and I do not know if she is going to lie down to wait for the eggs.


I have eight chickens, seven months old. They have been averaging seven or eight eggs a day. Yesterday I found seven eggs. This morning I found four (one colder, assuming it was from previous day). This afternoon I went out to collect what I thought would be five eggs max. I found 10! Now I am confused or are they totally confused? Any ideas? Oh, and it's winter in Alaska.


It does depend on the breed, of course. Some lay fewer eggs per year. Look up Bearded Belgium and Silver Dutch.


I have three chickens about nine months old. Two of them are now sitting on their nest, but have no eggs under them. What is going on, and how long do they stay there?

My third one is laying about an egg a day and is the only one out in the chicken yard. Can I remove the two sitting hens to make sure they get enough food? I did it twice but they go right back into the nest. Is there something wrong with them? The three are always well fed and have fresh water, but I am afraid. The two nesting ones don't get any. Please help!


I have chickens as pets and they are adorable. (two of them, so sweet!) They lay blue and green eggs, which are very good quality. Sweet little babies. God bless all chickens!


Does a hen need to be wormed?


i have a chicken that is one year old. i went to the nest and there were two eggs, so i think yes, hens can lay more then one egg a day. Hope this note will help someone. --maya


thanks. after the first lay and hatch of chickens, would the same chicken lay and hatch again? how many times do chickens and turkeys lay and hatch in a lifetime?


Our chickens just recently began laying eggs. Some mornings we will find 2 eggs in the same box. Just wondering if they were laid by the same chicken. Today we found 3 eggs together and my husband checked this morning and there were no eggs.


can a chicken lay more than one egg in 24 hours?


Does a chicken go through pain when laying an egg?


I am so excited. my chickens are just starting to lay. I guess I am easily amused but this is the first time I have raised them from day old chicks to laying hens.


today my chicken laid its first egg.


Our chickens have laid double yolk eggs--especially early in their ovulation cycles, so clearly a chicken can lay two eggs in one day. I would be surprised to see this last for long, however.


how many cc eggs do they lay a day?


a hen can lay until she dies. some may stop at three years.


i have just received a hen but i am worried as she is not laying. i do not know how old she is but someone says she has to get used to her surroundings. is this true?


To anon41534: Although chickens do need to breed in order to produce fertile eggs, interestingly, turkeys do not. If female turkeys don't mate with a male, or if they mate with a male who has non-viable sperm, she can still produce a fertile egg through a process called parthenogenesis.


My uncle, Gus Stern had a chicken hatchery located in Vineland, NJ in the 1940 - 1960 range. During 1956/57,he had a chicken that laid 362 eggs (official Trapnest record of Hunterdon County Egg Laying Contest)in one year. One egg each day for almost an entire year. She was known as bird #16-3 but was given the name Meg O'Day by someone from Rutger's Univ. When Meg died at the age of 2 1/2, my uncle had her stuffed and mounted then placed her on a shelf located over the TV in the living room of his house for all to see. He was very proud of Meg.

Meg was a featured exibit at the Museum of American Jewish History which was located on Independence Mall East in downtown Philadelphia, PA. There was an article printed in the Philadelphia Bulletin Discover Magazine on February 25, 1979. Check it out. --Elliott


i have a chicken that i think is laying two eggs per day also. she lays one large and one small egg.


yes, an egg must be fertilized to hatch.


your article on chickens is very informative but has left us with a family argument, which is: does the hen need a rooster to fertilize the egg to enable the egg to hatch? Regards, Robert


We are wondering the same thing about a chicken of ours (about the same age as Brett's) who goes off and lays her eggs in a different place than the nesting boxes, and it seems she has laid 2 or even 3 on one day. How is this possible?


my brother got two cross bred sussex hens. he gets on a regular basis 4 eggs one day and two the next day


We have four chickens about 24 weeks. This morning we have only noticed one going to lay and upon checking after half an hour there were 2 eggs in the same spot, both warm and one much smaller than the other, can chickens actually lay 2 eggs ?

I had been down to the hutch previous to this to remove an egg that had been laid earlier.
