Egg binding in birds: signs and what to do

An egg-bound bird is a hen that cannot pass an egg. Watch for straining, a bobbing tail, fluffed feathers and sitting on the cage floor. Call an avian vet now: a small bird like a cockatiel can go downhill within a few hours. Keep her warm, at 80 to 85 F, and do not try to remove the egg.

What are the signs of egg binding in birds?

Three signs turn up in nearly every vet source we checked: straining as if passing a dropping, a tail that bobs with each breath, and sitting fluffed up on the cage floor.

Others include a wide-legged stance, a swollen belly, a bulge at the vent, weakness, fast or open-mouth breathing, and few, no or bloody droppings. Some hens cannot grip the perch, or stop laying all of a sudden.

These signs overlap with other illnesses, VCA notes, so call whether or not you saw an egg coming.

What should I do if my bird is egg bound?

At home, your job is to keep her warm and calm until a vet sees her. None of the setup below should delay the trip.

Call an avian vet now
Say you suspect egg binding, so they are ready for her.
Set up a hospital box
Her travel carrier or a small box, lined with a soft towel.
Keep her warm and quiet
Cover all sides but one to block drafts, light and noise.
Aim for 80 to 85 F
A heating pad on low under or beside the box, towels between.
Add moist air if you can
A clean humidifier in the room, if you already own one.
Food and water on the floor
Shallow dishes right where she sits, since she may not perch.
Hands off the egg
Do not squeeze her belly, press on the vent or pull.
Covered carrier to the vet
A warm water bottle beside the carrier, at least three sides covered.

The 80 to 85 F (27 to 29 C) range is what the Association of Avian Veterinarians (AAV) calls ideal for most sick birds. Skip any heater that gives off fumes or smoke, the AAV adds.

A large egg can crowd her air sacs and speed up her breathing, LafeberVet notes, so watch her wings as well. Wings held away from her body, or panting, can mean she is too warm, so turn the heat down.

Vets pair warmth with humid air for an egg-bound hen, Merck and LafeberVet note. For a sick bird at home, Merck suggests a humidifier kept extra clean so mold cannot grow. If you do not own one, skip it rather than delay the trip.

Handle her as little as you can, the AAV advises. If she goes limp on the way, keep heading to the vet and have a passenger pull up our bird CPR guide.

Can I help my bird pass the egg at home?

Not by hand. Do not press on her belly, pull at the vent or try to break the egg. Merck warns that pressure on a bird's chest makes breathing hard. When a vet removes a stuck egg, Merck and VCA describe doing it with the bird sedated or anesthetized.

Skip online remedies such as oil or lubricant at the vent, or calcium by mouth. The AAV warns against any drug or remedy your vet has not prescribed, and against dripping liquid into the beak of a bird too weak to swallow. Beyond her usual food and water, give nothing by mouth unless your vet says to.

Is my bird laying an egg or egg bound?

Laying takes effort, so some pushing is normal. What sets egg binding apart is pushing that does not end, in a hen who looks unwell.

What you see	Can be normal laying	Points to egg binding
Pushing and tail bobbing	A wide stance and a strong tail bob while the egg comes, then it stops	Straining or tail bobbing that keeps going, with no egg
Droppings	Large, looser droppings around the time she lays	Few or none, or blood in them
Where she sits	On eggs she has already laid, still eating and drinking	Puffed up and drowsy on the cage floor, with no new egg
The vent	The lining can push out briefly as the egg passes, then slips back	Blood, an egg bulging there, or tissue that stays pushed out
Legs and feet	Steady on her feet, gripping the perch	Wobbly, cannot stand or grip, cold or pale feet
Laying pattern	Eggs in a clutch, often 2 to 4, sometimes more in cockatiels and budgies	Laying stops suddenly and she seems unwell

If you cannot tell, treat it as egg binding and call. The AAV lists waiting to see how a sick bird looks tomorrow among its mistakes to avoid.

Get to the vet now if

She keeps straining with no egg, sits fluffed on the cage floor, bobs her tail with fast breathing, or cannot stand or grip the perch. Go now, too, for blood from the vent or tissue showing there.

Why is egg binding so serious in small birds?

A stuck egg can press on blood vessels, nerves and her air sacs. LafeberVet links that pressure to cold, pale feet, weak or paralyzed legs and shock, and notes it can block droppings. VCA warns that a small bird can go downhill within a few hours.

There is good news too: PetMD says most egg-bound birds can be saved, and speed of treatment matters most. Many pass the egg once a vet gives warmth, fluids and other support.

What will the vet do for an egg-bound bird?

Once she is stable, an x-ray often shows the egg's size and position. Merck lists fluids, calcium and a warm cage with a humidifier as first treatments.

If the egg still will not pass, the vet may remove it with her sedated, or draw out its contents so the shell collapses. Surgery is for harder cases, VCA notes.

Which birds are most at risk of egg binding?

Any hen can become egg bound, but small species top every list.

Risk	Why it can matter
Cockatiels, budgies, lovebirds, canaries, finches	Every vet source we checked names small species like these first
Laying clutch after clutch	Merck notes most egg-bound hens are chronic layers, and repeated laying drains calcium
A mostly seed diet	VCA says seed diets run short of calcium and vitamins D and E
A first clutch, or an older hen	LafeberVet lists both among the causes
Overweight and inactive	Merck calls egg binding most common in these birds
Long days of light	Chronic layers often get more than 12 hours of light a day, Merck notes

Sources: VCA, Merck, the AAV and LafeberVet.

If any of this describes your hen, save an avian vet's number now, and add PetAid, the iPhone app we make, so bird first aid basics are a tap away.

How do I stop my bird from getting egg bound?

Most prevention means feeding her for laying and turning down the cues that tell her to lay. Plan the changes with your avian vet.

Change	What it looks like at home
A better diet	Move toward pellets with your vet's help. For small hens that lay a lot, the AAV suggests about half pellets, a quarter seed, a quarter vegetables and fruit
Calcium within reach	A cuttlebone in the cage. Supplements only if prescribed: the AAV says extra calcium outside laying may harm the kidneys
Shorter days	About 8 to 10 hours of light for a stretch your vet sets, then true darkness. Any light in the dark hours undoes it, the AAV warns
No nest	Take out nest boxes, shredding paper and any nook she is turning into a nest
No stand-in mate	Remove a mirror or toy she courts, and stroke only her head
A new setup	Move and rearrange the cage, and quiet any fountain a cockatiel can hear
Leave her eggs	Let her sit on eggs while she cares about them. Taking them away can prompt more laying

Light: VCA and Merck say 8 hours, LafeberVet 8 to 10; ask your vet how long. Other rows: the AAV, which also says to watch her weight, since birds do not eat in the dark.

Call your vet, though usually not as an emergency, if her eggs turn soft-shelled, misshapen or smaller, the AAV advises. If she keeps laying anyway, ask your vet about hormone treatment. After an episode, PetMD suggests at least 2 to 4 weeks away from laying triggers, ideally a full season.

Questions people ask

My bird lives alone. Can she still get egg bound?

Yes. A hen lays without a male; the eggs are simply infertile. Many owners do not know their bird is female, VCA notes. In standard grey cockatiels, hens are duller than males, with barred wing and tail feathers, LafeberVet says. For most other parrots, a DNA test is the surest noninvasive check.

How young can a bird start laying eggs?

Younger than many owners expect. LafeberVet puts puberty at 3 to 4 months in budgies and around 6 months in cockatiels.

It is the middle of the night. Who do I call?

The nearest animal ER, but ask first whether the vet on duty treats birds, since not every clinic does. The AAV suggests finding out now which local ERs see birds and posting their numbers at home.

She laid the egg on the way. Do we still go in?

Call the clinic before you turn around, and follow their advice. Merck notes that after a stuck egg comes out, another may follow by the next day.

There is blood in the cage. Is that from the egg?

It may be. The AAV lists blood from the vent or on the droppings as a reason to call your avian vet right away. If the blood is coming from a broken growing feather on a wing or the tail instead, see our blood feather guide.
