Egg Binding
What is it?
Egg binding happens when a female bird can't pass an egg. It is linked to calcium deficiency, poor diet, obesity, lack of exercise, or chronic egg-laying, and can quickly become life-threatening.
What signs should I watch for?
Signs to watch for include straining, tail bobbing; sitting on the cage floor, fluffed; swollen abdomen; lack of droppings; and leg weakness.
How is it diagnosed and treated?
Diagnosis uses an exam and X-rays. Treatment may include warmth, fluids, calcium, and medication to help pass the egg; sometimes the egg must be removed.
Can it be prevented, and what's the outlook?
- Proper diet, good lighting, and reducing laying triggers help prevent it.
- An egg-bound bird is an emergency.
