# Egg Binding in Birds

**Egg binding** is when a female bird cannot lay an egg — a life-threatening emergency. Signs include straining, tail bobbing, weakness and sitting on the cage floor. Keep the bird warm and call an **avian vet the same day**. Do not attempt home extraction.

## What is egg binding?

Egg binding (dystocia) happens when an egg becomes stuck in the reproductive tract. Without treatment, birds can die from shock, egg yolk peritonitis, or prolapse within hours.

According to the RSPCA, birds hide illness — egg-bound birds may look only slightly fluffed until they collapse. Same-day avian veterinary care is essential.

## Which birds are affected?

Any egg-laying female can be affected, including:

- Budgerigars and cockatiels
- Canaries and finches
- Lovebirds and parrots
- Hens in backyard flocks

Birds may lay eggs even without a male present. Chronic egg-laying increases risk.

## Signs of egg binding

| Sign | What to look for |
|------|------------------|
| Straining | Repeated pushing at the vent with no egg produced |
| Tail bobbing | Visible effort with each breath |
| Weakness | Sitting on cage floor, unable to perch |
| Fluffed feathers | Hunched, puffed-up appearance |
| Swollen abdomen | Distended lower belly |
| Reduced droppings | Blockage or dehydration |
| Lameness | Pressure on nerves from retained egg |

## What to do before the vet

1. **Call an avian vet immediately** — many practices refer to specialist clinics
2. **Keep the bird warm** — hospital cage or heated area (not overheating)
3. **Minimise stress** — quiet, dim environment; do not handle excessively
4. **Do not give calcium or oils without vet advice** — wrong treatment can worsen prolapse
5. **Transport in a secure, warm carrier**

## Veterinary treatment

Your avian vet may provide fluids, calcium, pain relief, warmth and humidity. Some cases need manual extraction, ovocentesis, or surgery. X-rays or ultrasound confirm egg position.

## Reducing future risk

- **Limit daylight** — excessive light triggers breeding behaviour; cover cages for 10–12 hours nightly
- **Remove nest boxes and breeding stimuli** unless intentionally breeding
- **Balanced diet** — avoid all-seed diets; ensure adequate calcium from pellets and cuttlefish bone
- **Discourage chronic laying** — rearrange cage, limit high-fat foods, consult your avian vet about hormonal options
- **Annual avian health checks** — discuss egg-laying history with your vet

## When to call the vet

**Same day** for any straining female bird, tail bobbing with weakness, or sudden collapse. Egg binding is not a wait-and-see condition.

## FAQs

### What is egg binding in birds?

Egg binding occurs when a female bird cannot pass an egg. It is life-threatening without prompt veterinary care — common in budgies, cockatiels, finches and parrots.

### What are the signs of egg binding?

Straining at the vent, tail bobbing, weakness, fluffed feathers, sitting on the cage floor, swollen abdomen, and reduced droppings. Seek same-day avian vet care.

### Can I help my bird pass the egg at home?

No. Egg binding requires veterinary diagnosis and treatment — which may include calcium, fluids, warmth, or manual/surgical removal. Home remedies delay life-saving care.
