Fairy Eggs and Tiny Eggs
A fairy egg, sometimes called a wind egg or witch egg, is a very small egg that usually contains no yolk. It happens when a bit of tissue triggers the oviduct to build an egg around nothing. This is most common at the very start of a hen's laying life and near the end of it. One or two is normal. A steady stream of them from a mature hen suggests a reproductive problem in that bird.
Most likely causes
- New layer
The system fires before yolk release is synchronized.
- End of a laying cycle
Older hens and hens finishing a cycle produce more of them.
- Stress or disturbance
Sudden disruption can trigger an out-of-sequence egg.
- Oviduct irritation
Tissue fragments can act as the seed the shell forms around.
What to do this week
- No action is needed for occasional fairy eggs from pullets.
- Keep laying conditions steady: quiet nests, consistent light, complete feed.
- Log the pattern by hen so recurring cases are visible.
When it is worth a closer look
- A mature hen lays only fairy eggs for more than two or three weeks.
- Fairy eggs plus a swollen abdomen, weight loss, or lethargy.

Common questions
Are fairy eggs edible?
Yes. They are usually white only, with little or no yolk.
Why do old hens lay tiny eggs?
As reproductive function winds down, out-of-sequence eggs without yolks become more common.
When a fairy egg is fine and when it is not
A fairy egg is a tiny egg, sometimes no bigger than a grape, and it often has no yolk inside. Keepers also call them wind eggs or fart eggs. They happen when a small bit of tissue or white sets off the egg making process without a yolk. In most flocks they are a one-off and nothing to worry about.
Who usually lays them
- Pullets just starting to lay, while their system finds its rhythm.
- Hens coming back into lay after a molt or a winter break.
- Hens near the end of their laying season.
- Bantams, whose normal eggs are small anyway. Do not mistake a normal bantam egg for a fairy egg.
What to check if they keep coming
- Work out which hen is laying them. Watch the nest boxes or note the shell color.
- Look at her overall condition. Feel the keel bone for weight loss and check the comb color.
- Check for mites and lice around the vent and under the wings.
- Look at her droppings and appetite.
- Review the feed. A complete layer ration should be most of the diet.
How to tell this apart from other problems
A small egg with a thin or rubbery shell points more to calcium or stress, covered on soft shell eggs. A hen who lays tiny eggs and then stops laying altogether, while looking quiet and losing weight, may have a reproductive or internal problem. The not laying eggs page walks through that side. If a hen's belly is swollen or feels like it holds fluid, that is a vet visit, not a wait-and-see.
When to call a vet
One or two fairy eggs from a healthy hen need no vet. Call an avian or poultry vet if a hen lays only tiny eggs for weeks, if she seems sick, or if she is straining often. Older hens with ongoing laying trouble sometimes have tumors or infections of the reproductive tract that only a vet can sort out.
Prevention
You cannot prevent the odd fairy egg, especially from new layers. You can make them less likely by keeping stress low, feeding a balanced layer ration, controlling mites, and letting pullets start laying at their natural age rather than pushing them with sudden extra light.
The flock and the egg itself
Fairy eggs are not contagious and do not mean the rest of the flock is unwell. A clean, intact fairy egg is safe to eat, though there is not much in it. Many keepers save them as a keepsake. They will not hatch, since there is no yolk to feed a chick.
Common questions about fairy eggs
Why is there no yolk in my tiny egg?
The egg making process started without a yolk being released, so the hen built a small egg around a bit of white or tissue.
Are fairy eggs a sign my hen is about to start laying?
Often, yes. Many pullets lay one or two before regular eggs begin.
Is it bad luck to get a fairy egg?
Old folklore said so, but it is just a normal hiccup in egg production.
