Best Chicken Breeds for Jumbo Eggs: A Working List

I have kept chickens for over a decade. I have sorted through hatchery catalogs, traded birds at swaps, and cracked enough eggs to fill a swimming pool. When people ask about jumbo eggs, they usually want a specific list. Here is that list, plus the things I learned the hard way.

What Actually Counts as a Jumbo Egg?

Most people guess by weight. A jumbo egg weighs at least 70 grams. Extra large runs 64 to 69 grams. Large is 56 to 63 grams.

The difference matters for bakers and for people selling eggs. A dozen jumbo eggs weighs nearly two pounds. That is a noticeable difference in the carton.

Here is the thing nobody tells you: breed determines the ceiling, but age determines the floor. A pullet’s first eggs are small. They size up over the first year. Many hens lay their biggest eggs in the second winter, not the first spring.

What Chickens Lay Extra Large Eggs

The search data shows this is the question everyone types. The short answer is that several Mediterranean and English breeds do it consistently.

These are the breeds I have personally raised that hit jumbo size with regularity:

Black Australorp

This is my top pick for a backyard flock. Australorps lay large to extra large brown eggs. They are calm, they handle heat well, and they keep laying through cold snaps.

The standard advice says they lay 250 eggs a year. My best hen beat that. She laid nearly every day from March to October. Her eggs ran 65 to 72 grams.

They are not the biggest eggs on this list, but they are the most reliable. That consistency matters more than an occasional giant.

Sussex

Speckled Sussex hens lay large brown eggs. The first year, you will see mostly large. The second year, the eggs creep up into the extra large range.

I keep one thing in mind with Sussex birds: they go broody. A broody hen stops laying for weeks. If you want maximum egg count, you have to break the broodiness or accept the pause.

Rhode Island Red

This is the workhorse breed. They lay large brown eggs that often hit jumbo size in mature hens. They are tough birds that forage well.

One observation that contradicts the standard advice: people say Rhode Island Reds are aggressive. Mine were not. They were pushy at the feeder, sure, but they never drew blood. The rooster was another story, but the hens were fine.

The standard advice exists because hatchery strains vary. Some lines are flighty. Pick birds from a reputable breeder and you get the calm ones.

Leghorn

White Leghorns lay the biggest eggs relative to their body size. A five-pound hen can drop a 70-gram white egg. That is a huge egg for a small bird.

They are flighty. They do not want to be held. They prefer to range wide and roost high. If you want a lap chicken, this is not it.

But if you want white jumbo eggs and you have space, Leghorns are efficient machines. They convert feed to egg mass better than almost anything else.

Barred Plymouth Rock

These lay large brown eggs with a good feed conversion. Mature hens push into the extra large category. They are cold-hardy and docile.

I have found Barred Rocks to be the most consistent layers through winter. They need less supplemental light than my other breeds. That is a practical advantage if you do not want to run electricity to the coop.

If you are still planning your setup, think about lighting. The coop light kit on this site covers the basics for extending winter daylight.

What Chicken Lays the Largest Eggs

If you want the absolute biggest eggs, you need the breeds bred for that specific trait. These are the heavy hitters.

Brahma

Brahmas are massive birds. The hens lay large to extra large brown eggs. Their eggs are not always jumbo, but they are consistently large.

The trade-off is time. Brahmas take longer to mature than most breeds. You will wait seven or eight months for the first egg. Some Mediterranean breeds start at five months.

Jersey Giant

This is the breed that answers the question of which chicken lays the largest eggs. They were developed in New Jersey specifically to replace turkeys on the table. The hens lay extra large brown eggs.

They are slow to mature. They eat a lot. They need tall fencing because they can fly surprisingly well for their size.

My Jersey Giant hen laid eggs that barely fit the standard carton. I had to use jumbo cartons for her eggs. She laid about three a week, not daily, but each one was a meal.

Orpington

Buff Orpingtons lay large brown eggs. Mature hens in their second year often produce jumbo sizes. They are friendly, cold-hardy, and go broody often.

That broodiness is the main drawback. You will lose egg production for weeks at a time. Some people use Orpingtons as surrogate mothers because they are so dedicated.

Chickens That Lay Large Brown Eggs

The search data shows many people specifically want brown eggs. That is a market preference. Brown eggs sell faster at farmers markets, even when they taste identical to white ones.

The breeds that lay large brown eggs are the ones I listed above: Australorps, Rhode Island Reds, Sussex, and Orpingtons. Add Wyandottes to that list.

Wyandotte

Silver Laced Wyandottes lay large brown eggs. They are reliable layers and handle confinement better than Leghorns. They are also beautiful birds.

One thing I noticed: Wyandottes are prone to putting on weight. They are not the most efficient feed converters. Watch their rations or you will have fat hens and fewer eggs.

Producing High Quality Jumbo Chicken Eggs

Breed gets you partway. Management gets you the rest. You cannot force a Leghorn to lay jumbo eggs, but you can ruin a Jersey Giant’s egg size with poor feed.

Here is what I do in my own flock:

• Feed a layer ration with at least 16% protein. The extra protein supports egg size.
• Provide oyster shell free-choice. Calcium is the raw material for shells. Skimp here and you get thin shells or small eggs.
• Keep the water clean and cold in summer. Hens drink less when water is warm, and that cuts egg size.
• Do not let hens get fat. Fat hens lay smaller eggs.

Feed quality matters more than most people think. The feed guide for egg quality goes deeper into the protein and calcium details.

Breeding for Larger Eggs

If you hatch your own chicks, you can select for egg size over generations. This is slow work, but it works.

Keep eggs from your largest layers. Hatch those. Cull the pullets that lay small eggs. Within three generations, you will see a measurable shift.

One thing people miss: egg size is heritable from the father too. The rooster’s genetics influence the daughters’ egg size. Pick a rooster from a line known for big eggs.

Incubation Notes for Large Egg Breeds

Large eggs need slightly different incubation conditions. The eggs have more mass, so they take longer to heat up and cool down.

I use a forced-air incubator for all my hatching. The flock size planning guide on this site helps you decide how many chicks to hatch in the first place.

For the incubator itself, I have had good results with the MATICOOPX 20 Egg Incubator. It has a built-in egg candler, which saves you from buying a separate tool. The automatic egg turner runs on a 60-minute interval, and it stops turning three days before hatch. That matches the natural pause hens take.

The external water refill is the feature I appreciate most. Opening the lid to add water drops the humidity instantly. That drop kills hatch rates. Refilling from the outside avoids that problem.

Check the current price on Amazon if you are in the market. The stable temperature from the circulating fan is worth the money for rare or expensive eggs.

Common Questions About Jumbo Egg Breeds

Do jumbo eggs have double yolks?

Sometimes, but not always. Double yolks are more common in young pullets whose hormones are still settling. They are also more common in breeds selected for large eggs.

Are jumbo eggs safe to eat?

Yes. They are the same as any other egg. The shell might be slightly thinner on the largest eggs, so handle them gently.

How many hens do I need for a dozen jumbo eggs a week?

Most large breeds lay four to five eggs per week. You need about three hens to get a dozen. That is assuming they are in their prime laying years.

Will my hens lay jumbo eggs forever?

No. Egg size peaks in the second and third years. After that, production drops and eggs get smaller. Most hens are retired by year four or five.

Final Thoughts on Big Eggs

Pick a breed that matches your climate and your patience level. Jersey Giants give the biggest eggs but take forever to mature. Leghorns give big white eggs but do not want to be pets.

I keep Australorps and Rhode Island Reds. They give me large to extra large brown eggs with minimal fuss. That trade-off works for me.

Egg size is not everything. A hen that lays consistently for three years beats a hen that lays one giant egg and goes broody. Keep that in mind when you pick your flock.
