Mr. L of East Coast had always wanted to own a swiftlet farm but he is afraid to go into it knowing that the successful rate is low if one has no experience. Therefore he started a small wooden Bh the size of 20 x48 ( 2 storey ) for experimental. If it works then he would invest into it and build a bigger concrete Bh perhaps a 3 storey 25x80.
He had spoken to me many times before he builds this Small farm. If I could remember it was a year or more ago. It was good that he had tried out this way and see it himself .
(structurally a very economical one)
It wasn't a good start but he had managed to pull in many birds after changing to the GS External sound. The Gs sound worked well many birds came and play everyday without fail. The only problem currently he is facing now is the temperature and of cause the limited internal space.
Prior to my visit Mr.L had just harvested the nests therefore it only left those that are new built. This simply build experimental Bh has more than 60 nests in a year plus after operation.
