Which Chickens Lay Double Yolk Eggs? Mystery Solved!

Post date |

Ever cracked open an egg and got a surprise double yolk? It’s like hitting the breakfast jackpot! I’ve been raising chickens for years, and the excitement of finding those golden twins never gets old. If you’re wondering which chicken breeds are most likely to give you this eggy bonus, I’ve got all the answers for you.

The Truth About Double Yolkers

First things first – there isn’t actually one specific breed that exclusively lays double yolk eggs. It’s more about timing and circumstances than genetics, though some breeds do have a higher tendency.

What Causes Double Yolks?

Double yolks happen when a hen releases two yolks into her oviduct instead of just one. Normally, a chicken releases a single yolk from its ovary, with another following 30-70 minutes later. But sometimes the timing gets messed up!

Here’s what typically causes this phenomenon

  • Young pullets just starting to lay: Their reproductive systems aren’t fully synchronized yet
  • Hormonal imbalances: Can happen in young or older hens
  • End of laying cycle: Mature hens nearing the end of their egg-laying years
  • Genetics: Some heavier breeds have slightly higher tendencies

Breeds Most Likely to Lay Double Yolkers

While any chicken can lay a double yolk egg, some breeds are more prone to this egg-cellent surprise:

  1. Rhode Island Reds – These productive layers are known for occasionally dropping double yolkers
  2. Buff Orpingtons – These big fluffy girls sometimes lay eggs with twins
  3. Sussex – Good layers that might surprise you with doubles
  4. Leghorns – These champion layers occasionally produce double yolks
  5. Heavy production breeds in general

One of my Buff Orpingtons laid three double yolkers in her first month of laying! She settled down after that, but those monster eggs were something to behold.

The Rarity Factor

Double yolk eggs are pretty uncommon. The odds are roughly 1 in 1,000 for a backyard chicken. That means with a dozen hens, you might expect about 2 double yolkers per year.

Interestingly, in the US, most double yolkers are discarded as “irregular” in commercial settings. You won’t find them in your supermarket carton. However, in the UK, you can sometimes find them for sale, and in places like India, specific chickens are actually kept to produce them!

How to Spot a Double Yolker

Not sure if you’ve got a twin yolk situation? Here are some clues:

  • Size matters: Double yolk eggs are noticeably larger and heavier
  • Weight: Normal eggs weigh around 1.7-2.1 ounces (48-59 grams), doubles are heavier
  • Candling: Hold the egg up to a light source and you might see two distinct yolks
  • Young layer: If you have a pullet that just started laying, chances increase

Is It Safe to Eat Double Yolk Eggs?

Absolutely! Double yolk eggs are completely safe to eat. In fact, you get twice the protein with those two golden centers. They taste just the same as regular eggs, though they might throw off your baking recipes if you’re counting on standard egg sizes.

Double Yolk Superstitions

People love attributing special meanings to double yolkers! Here are some fun superstitions:

  • In Wiccan lore, they’re considered good luck
  • Romany folklore says a double yolk means twins are coming if someone in the family is pregnant
  • Norse mythology takes a darker view – they predict death (yikes!)
  • Some believe it means you’re about to meet your soulmate

Can You Hatch Double Yolk Eggs?

It’s extremely rare, but not impossible. The issue is space – two chicks in one shell have limited room to develop. Usually, if fertilized, one embryo will be stronger and the other won’t survive. There have been rare documented cases where both chicks hatched, but it’s definitely the exception.

Double Yolk FAQs

Will a hen always lay double yolk eggs?

No, it’s typically a temporary phase, especially in young layers. Once their reproductive system syncs up, they’ll go back to single yolks.

Can I make my hens lay double yolk eggs?

Unfortunately, no. If it were possible, the egg industry would have figured it out by now! It’s a natural anomaly that can’t be forced.

Are there other egg oddities to watch for?

Yes! Your chickens might sometimes produce:

  • Wind eggs (or fart eggs): Tiny eggs with no yolk
  • Egg within an egg: A complete egg inside another egg
  • Bumpy shells: Eggs with irregular shell texture
  • Soft or shell-less eggs: Eggs missing their hard outer covering
  • Blood spots: Small blood specks in the egg (still safe to eat)

When to Worry About Double Yolkers

Most of the time, double yolks are harmless oddities. However, if you notice an older hen suddenly laying frequent double yolkers when she never did before, it might be worth monitoring her health.

In rare cases, it could indicate an ovarian issue. Watch for:

  • Signs of distress
  • Difficulty laying (egg binding)
  • Other health problems

My Experience with Double Yolkers

I’ll never forget when my favorite Rhode Island Red laid an absolute monster egg – it weighed nearly 100 grams! When I cracked it open, not only did it have two yolks, but one of the yolks was double-sized itself. Talk about an egg-ceptional breakfast!

Should You Breed for Double Yolkers?

While double yolk eggs are cool, I wouldn’t recommend selecting hens specifically for this trait. The extra-large eggs can be harder for hens to pass and may increase the risk of prolapse or other laying problems. Plus, the trait isn’t consistent enough to effectively breed for.

Conclusion

So there you have it! While no specific breed guarantees double yolkers, breeds like Rhode Island Reds, Buff Orpingtons, Sussex, and Leghorns might be more likely to surprise you with these eggy twins, especially when they’re young and just starting to lay.

Remember – any chicken can lay a double yolk egg, but it’s more about timing than breed. Young pullets just beginning their egg-laying journey or older hens winding down are your best bet for finding this breakfast bonus.

If you’re desperately seeking doubles, your best strategy is to get a few pullets from good laying breeds and cross your fingers during their first few months of production!

Have you had any double yolk experiences with your flock? I’d love to hear which of your chickens laid these special treats!

What Causes a Double Yolk Chicken Egg?So what causes a double yolk chicken egg?

A double-yolk egg occurs when two egg yolks are released into a hens oviduct too close together and end up encased within the same shell.

Generally about an hour after an egg is laid, the next yolk is released, but due to hormonal change or imbalance, an overstimulated ovary sometimes misfires and releases the yolk too early.

Therefore, the shell forms around both yolks and results in a single egg.

Its far more common to find double-yolked eggs from new layers or those hens on the tail end of their laying life.

It can be genetic, and therefore hereditary, and is more common in the hybrids and heavier breeds.

All About Double Yolk Chicken Eggs

Since commercially-sold eggs in the United States are sold by weight and also candled prior to packaging, any double-yolk eggs are discarded (although in the UK they are not) and you could go an entire lifetime eating store bought eggs and never encounter one.

However in Hong Kong and India, chickens are actually bred to lay double-yolked eggs that are highly sought after by customers.
