Is My Chicken Egg Bound? Signs and What to Do
An egg-bound hen strains, stands upright like a penguin, and goes downhill fast — this is a same-day, act-now problem.
Most likely causes
A stuck egg
What points to it: Penguin posture, tail pumping, straining, frequent nest visits with nothing to show, wet or protruding vent, walking stiffly or not at all, lethargy. You can sometimes feel the egg as a firm lump between the vent and keel.
What to do: Bring her somewhere warm and quiet. A 20-minute warm shallow bath (water to her thighs), gentle vent lubrication with plain vaseline, calcium if you have it (liquid calcium or crushed tums in a syringe-fed slurry helps contractions), then rest in a dark warm crate. Many hens pass the egg within a few hours of warmth + calcium.
Why it happened
What points to it: Oversized or double-yolk eggs, calcium shortfall (calcium drives the muscle contractions), obesity, a first-year layer's oversized early egg, or chronic soft-shell issues.
What to do: After she recovers: free-choice oyster shell, trim the treat budget, and watch repeat offenders — binding recurs in hens with the underlying causes unfixed.
Check these first
Confirm it's binding and not something else: feel gently for the egg, check for a droppings blockage or a prolapse (different emergencies), and note when she last laid. Isolate her warm regardless — a struggling hen gets picked on.
When it's probably nothing
A hen spending an hour fussing in the box before laying a jumbo egg is just having a Tuesday. Binding is the combination of straining plus visible illness — posture, lethargy, no egg.
