Have you ever walked out to your chicken coop and found an egg so massive that you did a double-take? Maybe you even snapped a photo to show your fellow chicken-keeping friends. Trust me, you’re not alone! As someone who’s been raising backyard chickens for years, I’ve had my fair share of “wow” moments when collecting eggs.
Let’s dive into why chickens sometimes lay these monster eggs what it means for your hen’s health and whether you should be concerned or just enjoy the extra breakfast material!
What Causes Chickens to Lay Extraordinarily Large Eggs?
The Double Yolk Factor
The most common reason for super-sized eggs is simple double yolks. When your chicken releases two yolks instead of one during the egg formation process the shell needs to accommodate twice the filling! This happens most frequently with
- Young pullets just starting to lay
- Older hens approaching the end of their laying cycle
- Hens experiencing hormonal fluctuations
I remember when my Easter Egger pullet started laying – her third egg was nearly twice the size of a normal egg and sure enough cracking it revealed two perfect yolks swimming side by side. My breakfast that morning was extra rich!
Reproductive System Basics
To understand the phenomenon better, let’s quickly look at how a chicken creates an egg:
- The ovary releases a yolk
- The yolk travels down the oviduct
- Albumen (egg white) wraps around the yolk
- Shell membranes form
- The calcium shell develops and hardens
When two yolks get released almost simultaneously or too close together, they can end up packaged in the same shell. It’s nature’s two-for-one special!
Is My Hen in Danger from Laying Huge Eggs?
This is probably your biggest worry – and it’s a valid concern. Laying eggs already demands a lot from a chicken’s body, and oversized eggs can put additional strain on your hen.
From the BackYard Chickens forum, I found a concerning story about an Easter Egger hen who regularly laid enormous eggs. The owner reported:
“Her eggs have been so hard for her to spit out that they come out rugged, mountainous, and lumpy looking. Yesterday, her egg even had deep scratch marks going down it as if the egg was being scraped up by whatever was in her vent.”
The poor hen was clearly struggling, even spending hours hunched in the nesting box trying to pass these eggs.
So yes, extremely large eggs can potentially harm your chicken if they become egg-bound or if passing these eggs damages their reproductive tract. But don’t panic – most hens manage just fine, even with the occasional jumbo egg.
How to Help a Hen Laying Painfully Large Eggs
If your chicken seems to be struggling with massive eggs, here are some proven strategies to help:
1. Adjust Their Diet
One of the most effective approaches is modifying what your chickens eat:
- Reduce protein intake – Too much protein can lead to oversized eggs. Consider cutting back on layer feed and adding more scratch grains
- Ensure proper hydration – Keep fresh water available at all times
- Add black oil sunflower seeds – The natural oils can help eggs pass more easily
- Provide plenty of calcium – While this won’t reduce egg size, it ensures strong shells that won’t crack inside your hen
A chicken keeper from the forum noted: “The large eggs are produced by too much protein. If it’s very cold out she is probably eating a lot to keep warm and taking in too much protein.”
2. Encourage Natural Foraging
Let your chickens do what chickens do best – scratch around for bugs, seeds, and greens. This natural diet tends to produce more reasonably sized eggs than a diet heavy in commercial layer feed.
3. Monitor for Health Issues
Keep an eye out for:
- Difficulty walking
- Extended time in nesting boxes
- Dirty or prolapsed vent
- Signs of distress
Types of Abnormal Eggs and What They Mean
While we’re focusing on large eggs, it’s worth knowing about other egg abnormalities you might encounter:
| Egg Type | Appearance | Cause | Concern Level |
|---|---|---|---|
| Double Yolk | Significantly larger | Hormonal fluctuations | Low |
| Soft Shell | Paper-thin, flexible shell | Calcium deficiency | Medium |
| No Shell | Rubbery membrane only | Vitamin D or calcium deficiency | Medium |
| Blood Spots | Red streaks or spots | Broken blood vessel | Low |
| Internally Cracked | Ridge or seam in shell | Damage during formation | Low |
| Two-Tone | Two-colored shell | Stress during formation | Low |
| Lash Egg | Bumpy, odd shape | Infection (salpingitis) | High |
The last one – lash eggs – are the only truly concerning type that requires immediate veterinary attention. They’re not actually eggs but infected material passed through the oviduct.
Are Monster Eggs Safe to Eat?
Absolutely! With very few exceptions, abnormal eggs are perfectly safe for consumption. Double-yolked eggs are especially prized for their rich flavor and extra yolk goodness.
I’ve found that my family actually gets excited when I announce “We’ve got a double-yolker today!” It’s become a special breakfast occasion at our house.
The only eggs I personally avoid eating are:
- Eggs with cracks (risk of bacterial contamination)
- Lash eggs (not actual eggs and indicate infection)
- Extremely dirty eggs (though some people just wash them)
Will My Hen Keep Laying Huge Eggs Forever?
Probably not! Most hens go through phases of laying abnormal eggs, but these typically resolve on their own. Young pullets usually settle into laying normal-sized eggs after their first few months of production.
If your hen is older and suddenly laying giant eggs, it might be a sign that she’s nearing the end of her productive laying life. This is normal and part of the aging process.
My Personal Experience with Jumbo Eggs
Last year, my Orpington hen, Buttercup, went through a phase of laying eggs so large I could barely close the egg carton! I was both impressed and concerned. After consulting with more experienced chicken keepers, I adjusted her diet slightly (less protein-rich treats) and made sure she had plenty of exercise time.
Within about three weeks, her eggs returned to a more normal size. She still occasionally surprises me with a double-yolker, but it’s no longer a regular occurrence that seems to cause her discomfort.
When to Seek Veterinary Help
While abnormal eggs are usually no cause for alarm, there are times when professional help is warranted:
- If your hen appears egg-bound (straining but unable to pass an egg)
- Signs of infection or illness alongside abnormal eggs
- Prolapsed vent (tissue protruding from the vent)
- Blood or unusual discharge from the vent
- Consistent laying of extremely malformed eggs
FAQ About Huge Chicken Eggs
Q: Can I hatch a double-yolked egg?
A: Technically possible but extremely rare! The embryos usually compete for space and nutrients, resulting in neither surviving.
Q: Do certain chicken breeds lay larger eggs?
A: Yes! Breeds like Orpingtons, Rhode Island Reds, and Jersey Giants tend to lay larger eggs in general.
Q: Are double-yolked eggs more nutritious?
A: They simply contain about twice the nutrients of a regular egg – double the yolk means double the good stuff!
Q: My hen laid an enormous egg with nothing inside but egg white. What gives?
A: This is called a “fairy egg” or “witch’s egg” – it happens when a bit of reproductive tissue breaks away and triggers egg production without a yolk.
Conclusion: Don’t Worry (Too Much)
Finding a massive egg in your nesting box is usually more of a curiosity than a crisis. Most hens handle the occasional jumbo egg just fine, and with proper nutrition and care, they’ll typically return to laying more appropriately sized eggs.
That said, always pay attention to your chicken’s behavior and physical condition. You know your birds best, and if something seems off, it’s better to be cautious and consult with an experienced poultry vet.

When You’re Raising Laying Hens, You May See Some Strange Eggs Like These
Egg abnormalities and deformed chicken eggs occur with almost every breed of hen at some point in her egg laying career. Eggs laid by non-commercially bred hens vary considerably in size, shape, and color. People who have a small flock of backyard chickens with several different chicken breeds can learn to recognize eggs from each hen. It’s easier for them to know who’s laying and who isn’t, how often and when, and which hen may be having health issues because of consistent abnormalities. For people like me who have a larger flock, it’s harder to tell and requires us to separate a suspected hen to determine her laying quality and quantity.
The Anatomy Of Egg Laying
If you butcher your own birds and any of them are of egg laying age (5 to 7 months for most all breeds), you’ll see the eggs waiting inside her. There’ll be a cluster of little tiny yellow specks that look like grains of sand with small pebble like ones around them, graduating in size, larger and larger. These are the yolks. Have you ever wondered how do chickens lay eggs? When the yolk for the day is ready, it enters the oviduct where it can be fertilized.
Next, the egg white is added, then it receives two membranes that help to keep the nutrients in and to keep its shape. Finally, the shell is put on and the egg moves to just inside her vent. The whole process takes about 24 hours. Now, she’s ready to lay! Boy will she let you know when she’s done it. My whole flock gets excited and cackles for each and every egg, every day. You would think they would be used to doing it and not put on such a show, but it’s a production of cackles and crows for every egg! This is a very basic and simple explanation of the egg production process and somewhere in this straightforward, yet complex process, things happen that cause deformed chicken eggs and egg abnormalities.
Just in way of a reminder, a pullet (a hen under a year old) will lay smaller eggs than she will as she grows and matures into a hen. Of course, age is the first thing that comes to mind since most chicken breeds begin laying between 5 to 6 months of age. As a hen matures, the size of her eggs and the frequency of her laying will increase. Once she begins laying, it usually takes her 7 to 10 weeks to work up to full production. Depending on the breed and the lifestyle of your hen, you can expect her to lay for up to 10 years. The average lifespan of a hen is 14 years. If your main goal is egg production, then you probably wouldn’t want to keep your hen past 3 to 4 years of age as this is the age range she will be most productive. When I have a hen who is unproductive for more than four months out of the year, I cull her. That is of course unless she is special.
