Egg Binding is a serious problem attributed to the inability of a bird to lay or expel its egg/s from its body.
It is observed that smaller birds including cockatiels are more susceptible to egg binding.
The usual cause of such inability is an abnormality in the egg's structure. Either soft shelled or abnormally larger in size, the stuck egg may kill your bird within seconds.
Lovely, my first cockatiel to succumb to egg binding, was all playful and active minutes before egg binding struck and killed her immediately.
The following are major causes of egg binding:
Lack of Calcium. Eggs are made of calcium. Being depleted of this element will cause hens to produce soft shelled eggs that are hard to expel. This happens when there is little or no calcium source within their diet, and even if there is a source, too many clutches laid within a small period of time will be too much for any small bird.
Overbreeding. More than two clutches a year places your bird at a high risk to encounter egg binding. Calcium and nutrient intake will not be able to catch up with the fast depletion of these nutrients due to excessive egg production.
Lack of Essential vitamins. Producing and laying eggs are stressful activities and Calcium is but a small portion of what a hen needs. Lack of other vitamins will lead to abnormally shaped egg that the cloaca is not designed to handle.
Age. A young bird, in the case of a cockatiel, below a year old, have a higher risk of egg binding due to the underdeveloped reproductive systems.
Prevention.
Apparently, given the list of causes, a responsible breeder can take steps to minimize it. Cuttlebone is the best and most trusted calcium source as it is natural, it also supplies necessary amount of iodine and most importantly, your cockatiels are more than willing to take them. They should always be available even when not breeding. Two or three times a week, soluble vitamins can be added to their water source. It is said that adding drops of vegetable oil to their seed dish can lessen the risk dramatically. For the overzealous breeders, remove the nest box after the second clutch to discourage further breeding until the next season.
Cure
Unfortunately, your veterinary is the only possible cure for your bird. Operation may be necessary and you don't have the tools for it nor the knowledge. The bird may be injected with calcium for cloacal contraction helping to expel the egg. With all these possible solutions the risk of losing your bird is still very high.
Always remember that breeding and egg laying is always an emergency situation. Do your best to stop egg binding before it happens.
