Open AI Chicken DoctorMost likely causes
1. Young pullet, first eggs
Immature reproductive tract + oversized first eggs.
2. Calcium deficiency
Weak shell muscles can't push the egg out.
3. Obesity
Fat deposits in the abdomen narrow the oviduct.
4. Oversized or double-yolk egg
Egg too large to pass.
5. Stress or sudden cold
Can interrupt normal contractions mid-lay.
What to check first
- Standing penguin-upright, tail-pumping or straining?
- Walking like a penguin, refusing to leave the nest?
- Lethargy, fluffed feathers, refusal to eat or drink?
- Gently feel between the legs near the vent, can you feel a hard egg?
- How long since she was last seen normal? (12+ hours is critical)
Home care that works
- Move her to a warm, dark, quiet space (90°F+ if possible).
- Soak her lower half in a warm Epsom salt bath (1 cup per gallon of water) for 20-30 minutes.
- Lubricate the vent gently with vegetable oil or KY jelly.
- Offer calcium, crushed Tums or liquid calcium gluconate (Calcium Plus).
- After the bath, return her to the warm space and let her rest. Repeat soak in 2 hours if no egg.
- Do NOT try to manually break or extract the egg, yolk spilled inside is fatal.
Call a vet if
- Egg not passed within 4-6 hours of warm soak + calcium.
- Hen is collapsed, gasping, or non-responsive.
- Visible prolapse (tissue hanging from vent).
- Foul smell from vent (peritonitis already started).
Frequently asked questions
How long can a chicken live egg bound?
Most die within 24-48 hours without help. Some die in 12 hours if the egg ruptures internally.
Can I push the egg out myself?
Never push or squeeze hard, you'll break the egg internally and cause fatal peritonitis. Warm soak + calcium + time is the only safe home protocol.

Emergency care for an egg bound hen
An egg bound hen has an egg stuck in her oviduct or vent. She may strain, pump her tail, stand like a penguin, sit in the nest for hours, or go quiet and fluffed. This can turn deadly within a day or two, so act now.
Right now
- Bring her inside to a warm, quiet, dim crate.
- Gently feel her lower abdomen and around the vent. You may feel a hard egg.
- Give her a warm, shallow bath for about 15 to 20 minutes. Warm water helps her relax.
- Dry her well and keep her warm.
- Offer water and let her rest in the dark.
Some keepers apply a water-based lubricant around the vent. Calcium can help muscles contract, but ask a vet before giving more than oyster shell, since the right product and amount matter.
What not to do
Never pull the egg. Never break it inside her unless a vet guides you, because sharp shell can cut her and broken contents can cause infection.
Look-alikes
Straining with tissue showing is prolapse. A swollen, squishy belly with a penguin stance can be egg yolk peritonitis. A hen sitting flat and growling is likely broody.
When to call a vet
Call an avian or poultry vet if she has not passed the egg within a few hours of care, if she is weak or breathing hard, or if you can see the egg but it will not move.
Prevention
Layer feed as the main diet, oyster shell on the side, healthy weight, and not too many treats. See the egg binding guide for more.
Common questions about egg bound chickens
How long can a chicken be egg bound?
Not long. Without help, many hens become critical within a day or two.
Can an egg bound chicken still poop?
Sometimes not, because the egg can block the vent. That makes it more urgent.
Why do hens get egg bound?
Large eggs, low calcium, obesity, cold, and very young or older hens all play a part.
