Egg Binding
An egg gets stuck inside the hen. She strains, walks upright like a penguin, and stops eating. Untreated egg binding past 24 hours is often fatal.

Symptoms
- Straining to lay
- Tail pumping
- Walking penguin like
- Lethargic / not moving
- Not eating
- Pale comb
Treatment
Soak the hen in a warm Epsom salt bath for 20 minutes. Dry, then warm her in a quiet box. Lubricate the vent with KY jelly or vegetable oil. Give a calcium boost (crushed Tums or liquid calcium). If she has not laid in 6 hours, call a vet.
Prevention
Feed a balanced layer ration with oyster shell free choice. Avoid sudden lighting changes that trigger early or oversized eggs. Manage weight, obesity is a major risk factor.
Getting an egg bound hen through the next few hours
Egg binding means an egg is stuck somewhere in the hen's oviduct or near the vent. She cannot pass it, and the pressure can block her droppings and press on her organs. Some hens pass the egg with a little help. Others need a vet. The longer it goes, the worse the odds.
Signs that point to egg binding
- Straining or pumping the tail with nothing coming out.
- Standing upright like a penguin, or walking with a wide waddle.
- Sitting in the nest box for hours, coming out and going back in.
- Fluffed up, quiet, eyes half closed.
- No droppings, or small wet ones.
- A hard lump you can feel low in the abdomen.
What to do, in order
- Bring her inside to a warm, quiet, dim spot. Stress and cold make it worse.
- Give her a warm, shallow soak, enough to cover the vent, for a while. Hold her gently and keep the water warm, not hot.
- Dry her well and put her in a dark crate with a towel.
- Offer water. If she will drink, that is a good sign.
- Give her a few hours of quiet and check back.
Ask a vet before giving anything beyond oyster shell. Calcium can help muscles contract, but the type and amount matter.
Things to avoid
Do not try to pull the egg or reach inside her. Do not break the egg yourself unless a vet is talking you through it, since sharp shell and egg contents left inside can cause injury and infection.
How to tell this apart from look-alikes
A broody hen also sits in the nest for hours, but she flattens out, growls and puffs up rather than straining. Tissue sticking out of the vent is a prolapse, which can happen during or after binding. A swollen, squishy belly that feels like fluid rather than a hard egg points more to egg yolk peritonitis.
When to call a vet
Call an avian or poultry vet if the egg has not passed within a few hours of care, if she is getting weaker, breathing hard, or cannot stand. A vet can use medication, help pass the egg, or remove it safely.
Prevention
- Feed a complete layer ration, with oyster shell on the side.
- Keep treats and scratch to a small share of the diet.
- Keep hens at a healthy weight and active.
- Let pullets start laying at their natural age.

The flock and the eggs
Egg binding is not contagious. If one hen keeps getting bound, ask a vet about why, since some hens have an underlying problem. If she gets medication, check the product label or ask a vet before eating her eggs.
Common questions about egg binding
How do I know if my chicken is egg bound or broody?
Broody hens flatten and growl. Egg bound hens strain, pump their tails and seem unwell.
Can a hen die from being egg bound?
Yes, if the egg is not passed. Act quickly and call a vet if care does not work.
Will a warm bath help an egg bound hen?
It often helps her relax and can help the egg pass, but it is not a guarantee.
