Some causes of infertility in canaries

Canary breeding is fascinating and many people decide to tackle this task in their own homes. Most of the time chicks are obtained without problems, but there are also cases in which the couple achieves the mating and laying of eggs, but those eggs are not fertile.
Sometimes the cause is the parents . It is very important to prepare them for about 3 months with a well-balanced diet, with an adequate protein content (excess is also bad) and with a complete vitamin profile. At this time some natural supplements are very good, such as wheat germ, couscous, germinated seeds. In the last month it is good to also add fresh vegetables, which are very nutritious and do not cause weight gain. Rinse the vegetables with drinking water or add a drop of bleach per liter.
Fertility increases if the couple is waited to join until the female is in optimal condition for breeding at the beginning of the season. This is noticeable when she has already prepared her nest and removes it to give it a suitable shape, it is also seen that she crouches inviting the male to mount when she hears him sing. You will see that the skin around its cloaca turns reddish. You can add vitamins E and B to her diet to help her prepare. If the time is right you will see that between 1 and 2 weeks later they will start to put. If you put them together ahead of time, they may lay clear eggs. It is better if one of the parents is experienced. During the breeding season they re-mate several times even with chicks in the nest, so that it is no longer necessary to separate them as long as you want them to continue reproducing.
The nest must be wide so that when covering it on the inside it is not too narrow, causing the chicks to fall. You should disinfect it before putting it in the cage or discard it when dirty if it is not washable. Secure it well so it does not move or tilt.
The weight of the birds is also a factor to take into account when breeding. A male who is obese or too thin may ignore the female. Another problem that can occur is that the couple is incompatible and even if they are ready, they do not seek to mate. In this case, you should separate them and try again about 15 days later or change the male.
After mating, the female begins to lay eggs one by one per day for a total of between 3 and 5. The first 2 days she generally does not sit to incubate them , but from the third day she remains in the nest and only gets up to eat and relieve yourself. When with the male, he can bring food to the nest.
The eggshell is important too; if it is too thick it will not allow good ventilation of the interior, but if it is too thin the egg can dehydrate or break more easily. It will also allow bacteria to enter, causing the egg to rot. This depends on genetics and proper nutrition and supplementation with calcium and vitamin D3 from the mother. Hygiene of the nest , materials and your hands is very important before handling the eggs to avoid infection.
The temperature and humidity are also very important. If the temperature is too low or the female does not brood enough, the embryos can die inside the egg. The excess of humidity favors the colonization of bacteria, while the lack of humidity makes it difficult for the chicks to hatch and hatch.
As you can see, there are many factors to analyze when detecting a fertility problem. It is not an easy task, but once you can identify the problem, the reward will be healthy youngsters.
