You Might Find One (Or More) Of These Odd Eggs In The Nest Box

One of the many surprises that come with keeping chickens is the appearance of odd eggs in the nest box from time to time.

For those of us who grew up with grocery store eggs, we’re used to a highly curated and edited egg carton. Only the biggest and most perfect eggs ever made it from the farm to the supermarket (and still do).

But I say that nothing is perfect, and odd eggs are fun! Here are a few of the most common egg oddities.

Soft-Shell or No-Shell Eggs

You see treasure in the nest box, and you reach for it. And then—squish! The egg in your hand bursts open like a water balloon!

When hens are depleted of calcium, their shells will start to show it. Some of these odd eggs are laid without shells completely so that only the inner membrane is holding the egg’s liquids together. Other times, eggs have soft spots or weak points but an otherwise hard shell.

If you see any variation on these eggs, it’s a good reminder to refill the oyster shell container and keep it full and available at all times.

Multiple Yolkers

As the name would suggest, a multiyolker egg may house two (or more!) yolks within the same shell, and you can imagine that these eggs have to be pretty large to hold so much volume! Double-yolked eggs are the most common and occur when ovulation moves faster than normal, sending two yolks out at the same time.

They become encased in the same shell before the hen can produce a new one.

Certain hens have proclivities to laying double-yolkers. You’ll soon learn that hens that lay multiyolked eggs will do so more frequently than other hens. This is normal, but it can be cause for concern. Watch these birds closely as they’re more likely to have future reproductive issues.

Tip: Skip the double-yolk eggs for any hatching goals, if you can (development won’t go well in the incubator), but do enjoy the extra omega-3s and vitamin D from the extra yolks!

Calcium Deposits

Rough spots, bumps and blemishes are completely normal for chicken eggs. Not all eggs will be perfect.

Hens that lay these eggs may just need a little boost in calcium. Oyster shells offered free-choice every day, all day, will help remedy this ailment.

Wind Eggs

This oddball also goes by the name “fairy egg,” “fart egg” or “rooster egg.” These unusual orbs are incredibly tiny and almost always yolkless. They’re laid by young pullets that are just getting their egg-laying machinery up and running.

There won’t be many more of these once your hens mature a bit, so enjoy while you can!

Malformed Eggs

Occasionally, you’ll notice an egg that has a smooth, hard shell, no discoloration or blemishes, but it’s a really strange shape.

Maybe it’s very long and slender. Maybe it’s squat and round.

Don’t worry about these funny-looking eggs for eating, but do avoid hatching them. These eggs aren’t prime real estate for a developing chick embryo.

One joy to take from eating farm-fresh eggs from your own flock of hens is that nothing will go to waste—not even those funky, weird eggs!
