My instant reply was "NO". First thing that struck my mind was...."Is the situation so bad that there were no more Swiftlets in the sky to attract that he has to resort to cross fostering?" Or he is so unskillful that he can't attract any Swiftlet to his Swiftlet farm".
I don't encourage people selling Swiftlets eggs and strongly again those whose throw away eggs during harvesting. It is totally inhuman. There are throwing the eggs in the name of protecting their Swiftlet farms from competitions.
By doing this in long run the whole Swiftlet population of an area would decline. History has shown, the Jawa Island was facing the same problem many years ago forcing Swiftlet farmers to venture to new places to establish new farming. From Jawa many moved to places like Pontianak, Samarinda, Balik Papan, to name few.
Before you buy Swiftlets eggs do you know how to handle them prior to putting them in your Swiftlet farm? Many would have thought easy, same as buying chicken eggs from Super Market and bring them home. Well it is not as easy as you think.
Since we are talking about Swiftlets eggs, well let me give you some tips on how to select Swiftlet eggs. I had learned all these through my painstaking experience. At that time, many years back no one would willing to teach or give tips about selecting Swiftlets eggs. I guess even now ....except me ha ha ha ha....
Firstly, you much know how to identify and differentiate them. If you are not familiar with what you are buying you may ended up buying the wrong thing.
Swiftlet eggs are white in color with a slight light blueish tone. Seriti eggs are are white with a little of deep brown spots. Those who go to Indonesia to buy Swiftlet eggs must me be careful or you may ended up with many Seriti eggs. If the seller knows that you know very little about Swiftlet eggs selection they would mix the Swiftlet eggs with other eggs.
Select those that are in good oval shape. Odd shaped or oversize ones shouldn't be selected. The shell surface should be smooth and without hair line cracks. We do bring along magnifying glasses to check the eggs. Eggs with sediments and dirt normally wouldn't hatch.
In order to know the quality of the eggs a flashlight process is needed. In old days people are using candle. It is to see the inside of the eggs. The egg yolk should be in the center and stable. There shouldn't be blood spots inside. Those with blood spots would have a lower success rate of hatching.
Well there are more to it but I guess that is enough for you
to learn in order not to let someone fooling you.
Good Swiftlet farming All.
