The Beatles coined this saying in “I am the Walrus”!
A while back I encountered this egg with a feather stuck to it in a packet of eggs I bought from Waitrose!
This Saturday I visited High Wycombe, and was surprised to find this morning that in a packet of eggs from Iceland, was yet another chicken feather!”
A chap in this video shows you a chicken laying an egg, for children but I have never seen this before!
Whilst on this subject here is a full explanation of how eggs are produced by a chicken!

- Interesting Facts About Chickens Laying Eggs
Domesticated chickens have been providing humans with eggs for nearly 8,000 years, but having access to freshly laid eggs is no longer restricted to those living in the country. For the last few decades, the idea of the “urban farm” has seen an increasing number of suburbanites keeping their own poultry. With this renewed interest, you’re not alone in asking: How do chickens lay eggs?
How Do Chickens Lay Eggs?
An Eye to Behold
Funnily enough, the whole egg laying process begins with a small gland near the chickens’ eye. This tiny gland is light receptive and when it registers light (either natural or artificial), it triggers the release of an egg cell from the chicken’s ovary.
This egg cell travels to the uterus, where it will eventually grow into the egg yolk. Meanwhile, the chickens’ uterus gradually fills with a jelly like substance, called albumin, more commonly known as the “egg white”.
Seal the Deal
A membrane then begins to develop around the perimeter of the uterine walls, effectively sealing in the egg yolk and albumen. In time, a combination of calcium, salt and water rims this membrane to form a sturdy outer shell.
Let’s Get Physical
Once the egg is fully formed, the real work begins. The chickens’ muscles will start to contract in an effort to release the egg, forcing the egg to move down the vaginal canal towards an external opening, called a vent.
An Unexpected Journey
This vent is also connected to the intestinal canal and is used by the chicken to expel waste. Mid-way through its journey, the egg will reach an internal flap, called a cloaca. The cloaca is like a valve, which only allows one canal access to the vent at a time. Once the egg reaches this point, the cloaca valve descends and blocks the intestinal canal.
Bend and Stretch
Once the egg has almost completed its journey, the chicken will stand up and then lower its back end, which causes the vent to open as wide as possible.
The Little Miracle
The strengthening contractions essentially turn the chickens’ canal and cloaca inside out, forcing the egg to drop free onto the ground. Ta da! An egg has been laid.
Interesting Facts About Chickens Laying Eggs
Why Are Chickens Eggs Shaped like…Well, Chicken Eggs?
Did you know that the distinctive shape of a chicken’s egg actually mirrors the shape of the chickens’ uterus? The shell forms along the edges of the uterine wall, so the end result is just a mirror image of the space it was formed in. That’s why all chicken eggs are roughly the same shape.
Do Chickens Lay at the Same Time Every Day?
A lot of people assume chickens lay bright and early every morning. In fact, they actually work on a 25 hour cycle, so every day the egg will arrive around 1 hour later than the day before. But because chickens won’t lay in the dark, once their laying cycle reaches dusk, they will skip a day of laying and then the time cycle will start all over again the next morning.
What Do You Call the Tiny Eggs That Chickens Sometimes Lay?
Periodically a chicken may lay a tiny, useless egg. This happens when the egg passes too quickly through the chickens’ oviduct, and poultry farmers refer to these as “fart” or “oops” eggs, although perhaps not the official scientific name for them.
What If Chickens Won’t Lay in Their Nest Box?
Chickens, surprisingly, can be trained by example. If you have a chicken that lays her eggs wherever she feels like it, leave either a fake or real egg in the designated nesting box. The chicken will get the picture and start laying there instead.
Chickens Eat What?!
Yes, it’s a bit disturbing, but chickens will occasionally eat eggs. Generally this only happens if an egg is accidentally broken, and it’s nothing to worry about. However, if you have a chicken that starts breaking eggs deliberately so they can eat them (Hannibal Lector style), then it’s best to remove that particular chicken from the flock.
