If the egg is completely felt and near the cloacal opening, it might be gently extracted. 1 - 2 drops of pure edible oil careful with a pipette inserted, supports the action.

What is Egg Binding in Birds?

If a female is unable to expel a developed or partially developed egg through weakness or disease we speak about egg binding. Egg binding is not direct a disease, and can have many causes. Some kind of birds, such as budgerigars, canaries, cockatiels, finches, and lovebirds most frequently have problems related to egg laying, although any bird can become egg binding. The formed egg is stuck in the oviduct or the cloaca. The egg may be stuck near the cloaca, or also further inside. A too late detection and treatment may lead to the death of the bird.
Soft eggs and other egg deformities can lead to Egg Binding

What are the causes for an Egg Binding?

- The condition is frequently the result of malnutrition. Seeds are often poor in vitamins and minerals, especially calcium. Calcium is not only used by the body for building the shell of the developing egg or for strengthens the bones. Adult birds suffering from calcium deficiencies may become weak or uncoordinated. Especially laying females that are not properly supplemented are at highest risk for calcium deficiency disorders. Acute hypocalcemia in laying females leads to result in weakness and egg binding. Calcium also has an effect on the function of the muscles. If too little calcium is taken up by the bird and consumed for a perfectly developed egg, it can lead to a deficit for the proper functioning of the laying muscles (muscle relaxation), because the female needs also calcium for the muscle action to expel the egg. The calcium metabolism by the body is linked to phosphorus and vitamin D. Therefore adequate amounts of these nutrients are necessary for the proper utilization of calcium. The right ratio of calcium and phosphorus are in equilibrium 2:1. (0.5:1 to 2.5:1) can be tolerated. Vitamin D3 is required for the absorption of calcium into the bloodstream from the intestinal tract. (also read below about the side-effect of the Calcium-Phosporus Ratio in young birds)
Without vitamin D3, all calcium we offer our birds passes right through the body without being absorbed. In outdoor aviaries with access to sunlight our birds are able to produce D3 via a chemical reaction to sunlight. In indoor aviaries or indoor breeding cages is this chemical reaction not possible, because of missing direct sunlight. Sunlight through a window is not sufficient. The ultraviolet light needed does not pass through window glass. Additional artificial full spectrum lights (Daylight, 6500 K[elvin] ) can help but some studies have shown that the ultraviolet is only at sufficient levels at less than one foot from the light source. For inside birds, a D3 supplement is always recommended. Read more about: Artificial Lighting in a breeding room...>

How to  treat Egg Binding?

The inability to pass the egg quickly results in the death of the female. The best way in the initial stage is increasing the humidity and the heat. The hen should be separated in a hospital cage at 30 to 35 degrees Celsius. If a hospital-cage is not available an infrared lamp is also useful. Often then the egg is laid within a short time, as the heat caused a relaxation of the muscles. In addition, some edible oil (1-2 drops) is carefully introduced into the cloaca. If the treatment is successful, the female may no longer be used in the current breeding year, because the bird must have a complete recovery. A granted break until next year is recommended and it is important to assess the nutritional problems that caused this problem in the first place. In any case is it dangerous to attempt to breed with this female again until the nutritional deficiencies have been addressed. The female must create reserves again with sufficient supply of minerals and vitamin, because egg binding is almost always the result of an inadequate diet or mangle of breeding prerequisites.
In addition to the Calcium-Phosporus Ratio: Young, growing birds fed high-calcium diets can develop kidney problems leading to kidney failure and mineralization. In addition, high calcium levels without increased levels of manganese and zinc will interfere with the absorption of these trace elements. If too much phosphorus is provided, low calcium levels will result. The excess phosphorus will bind with calcium in the intestine to form an insoluble chemical, calcium phosphate. The remaining phosphorus is still absorbed, but blood calcium levels will be low.
Normally the mucus membranes around the vent must be soft and flexible. For this the fat based vitamins are primarily responsible for this condition, most notably linoleic acid and Vitamin A and E. Is there a shortage, the oviduct becomes dry and hard. Some avian vitamins do not include the fat based vitamins, so it is important to supply a separate source for these vital nutrients. These essential fatty vitamins can be found in many of the oily seeds such as safflower seed, sunflower seed, and especially niger seed. - Another cause of a bad condition is when the female is too young. In this case the body of the female not grown sufficiently to allow the easy passage of a developed egg. To prevent this, only females with an adequate breeding condition should be selected for the breeding. In females, which are too young the egg binding often ends fatally. At minimum age of one year should always be respected in small birds, such as finches or canaries. With parakeets and parrots is to be considered that they continues to grow in size for 2 or more years. This depends on the type and size of each individual breed. In the interest of animal welfare this should be considered. - As well but rare, the oversize of an egg can be responsible for an egg binding. - An egg travelling sharp-end first through a bird is also more likely to tilt and wedge, resulting in egg binding. - A partially developed egg with a rough shell, soft shell or no shell and also a deformed egg cannot pass the oviduct. - Also an infection of the oviduct may cause for egg binding. - Also too frequent oviposition can lead to egg-bound. At most 2 until 3 times must be observed, to ensure that the bird health are not impaired. Multiple clutches often lead to deficiencies and weakening of the metabolism. If it is difficult to finish the breeding after the second or third nest, the nest should be removed. If that is not enough, the couple must be separated.

How to recognized Egg Binding?

A female bird with egg binding, one recognizes at first by failing laying experiments. It tries to excrete the egg by strong pressing. As a result that large and thin excrement are eliminated, which are often mixed with blood. Affected females are nervous and restless, they often change the seat, sitting with legs spread wide on the perches or teetering with the tail. Pressure on nerve plexuses can cause paralysis. At a later stage affected females sit completely exhausted on the floor. Often, when palpating the abdomen, a slight curvature can be detected. If no fast treatment occurs, the female falls into shock and dies. Under certain circumstances, it can come to a prolapse by strong pressing.

The Calcium reserves of a Zeba Finch Scientist reported that zebra finches will deplete the calcium reserve after the 5th egg. The study showed a five-egg clutch has a total calcium requirement of 89 mg, but the total calcium reserve of a female is only 90 mg.
