Egg binding occurs when a female bird is unable to pass an egg that has formed in her reproductive tract. It is a life-threatening emergency that requires immediate veterinary attention. Prevention focuses on proper nutrition, environment management, and recognizing risk factors early.

Calcium deficiency is the primary dietary cause of egg binding. Without adequate calcium, the muscles of the oviduct cannot contract forcefully enough to expel the egg, and the eggshell itself may be soft or malformed. Ensure your bird receives sufficient calcium through a balanced pellet diet, cuttlebone or mineral block access, and calcium-rich vegetables like broccoli and kale. Breeding females and chronic egg layers may need additional calcium supplementation as directed by an avian veterinarian.

UVB light exposure is crucial because birds need UVB radiation to synthesize vitamin D3, which in turn is necessary for calcium absorption. If your bird does not have access to unfiltered natural sunlight, provide a full-spectrum avian UVB lamp positioned according to manufacturer guidelines. Window glass filters out most UVB, so indoor light alone is not sufficient.

Discouraging chronic egg laying reduces the risk significantly. Limit daylight hours to ten per day using cage covers or room darkening, remove nesting materials and any objects the bird treats as a nest, avoid petting the bird on the back and under the wings, and rearrange the cage periodically to reduce territorial comfort.

Obesity increases the risk of egg binding because excess fat deposits compress the reproductive tract. Maintain your bird at a healthy weight through proper diet and ample exercise.

Know the signs: straining on the cage floor, a swollen abdomen, fluffed feathers, labored breathing, lethargy, and loss of appetite. If you suspect egg binding, keep the bird warm and contact an avian veterinarian immediately. Do not attempt to extract the egg yourself.
