Why your hen laid a tiny egg, otherwise known as a fairy egg

It's not uncommon for a pullet or hen in your flock to lay a tiny egg that's around a quarter of the size of a regular egg. 

These tiny eggs are often called fairy eggs, but other names include:

  • Dwarf eggs
  • No-yolkers
  • Wind eggs
  • Fart eggs
  • Cock eggs (in the old days some people believed these tiny yolk-less eggs were laid by roosters!)


What do fairy eggs look like?

A fairy egg may have almost nothing in it, or it may have a meat spot as the core, or if it's on the larger side it may have a teeny tiny ~2cm diameter yolk inside.

Fairy eggs can weigh 10 to 20g, some are larger, around 30g. They are usually rounder in shape, like a mini golf ball.

If they are laid with a dark brown shell, often the pigment is concentrated and looks spotty.

Why do fairy eggs occur? 

Fairy eggs can occur when a pullet is starting to lay for the first time. She's gearing up for her first egg-laying season and a false start with a fairy egg or two is not a big concern. 

Fairy eggs are rarer in older, mature hens. But if it is, it's often at the end of their laying season, just before moulting. 

A fairy egg forms when a piece of reproductive body tissue or a blood clot separates from the oviduct wall. The hen's egg-producing glands don't know that this tissue is not a yolk, and proceeds to create albumen (egg white), membranes and a shell around it, as it travels through the oviduct. 

What do you need to do?

Ensure you are feeding your flock is being fed a good quality layer feed (I always advise 16%+ protein for layers), clean water, access to greens daily and minimising stress in the hen house. 

If you're getting multiple fairy eggs in a mature hen, it could be worth a vet visit to ensure there's nothing wrong with her reproductive tract.
