I received many queries from my readers about Duck eggs as aroma for farms. My advise is know what you are doing.
The effect of putting something that you have no idea of may be costly. The stink smell from the Duck eggs would do permanent damage to your farm internal environment at the same time invites predators especially big lizards (tokek).
Naturally Lizard loves eggs. The smell of Duck eggs attracts lizards to the farm. They will eat the swiftlet eggs. Getting rid of them is not easy. This will make birds avoiding your farm.
Below is the comment from a book written by a well known person in the Swiftlet farming industry of Indonesia " Drs.Arief Budiman . The history of indonesia Swiftlet farming could be tracked back to as early 19th century.( Below is the Bahasa Melayu version)
(Mixing Duck eggs, honey and fish oil is a Myth. For sure it will invite predators which we are avoiding)
Hope this will clear the air about all those Duck eggs. This Duck eggs issue is not new for those who have been long enough in this industry. The idea originated from Indonesia.
It has been debated many years ago in Indonesia and the trial & test were done many years ago and the result shows it has no effect on attracting birds but making your farm stink! That is for sure guarantee.
How about using the century eggs as a base for aroma? It looks good isn't it? If it doesn't work then at least you can eat it..... the lizards , cockroaches, ants, etc all are waiting for you to apply the aroma that contain Duck eggs.
This will invite predators. Red ants love Duck eggs as it contains protein....so does LIZARD!
