Hello. I have a question: I want to buy an indie duck, but the seller already has no drake. I wonder if the eggs will be fertilized? How much time is around, because they now live with a drake and the owner says that he is trampling them? (Helena)
Good day, Elena. Of course, fertilized eggs of musk ducks will not be if they live without a drake. But after weaning from the main herd, where the male was present in their harem, the fertility factor will persist for about 10 days. It is such a period of time that a spermatozoid, once in the oviduct, will be alive. But his activity, as you understand, will fade away every day.
It is important to take into account that such a maximum period, namely 10 days, the viability of the sperm will be maintained only if the necessary requirements are met.
- The first is the number of heterosexual ducks. In the former herd, the owner should have no more than 6 females per male.
- The second is the season of the year. What I mean? It is very important to take into account the period when you will acquire a bird. This is due to the fact that the sexual instinct in musky drakes appears seasonally. And this affects the quality of fertilization. So, in spring (April-May), this figure reaches 96-97%, but in summer (July-August) it drops to 50-55%.
Another important factor in your case is the living conditions of the bird. A high rate of preservation of life of the sperm depends on the feeding and living conditions. Fertility may not persist for more than 2–3 days if the duck lacks vitamin and mineral substances. Another factor that reduces the time of sperm activity is the accuracy and tightness of the site.
If all aspects are taken into account by the owner, then about 10 days after the last meeting with the male, your females will carry fertilized eggs.
