Finally, my BH was built successfully!
It is a huge 4 stories bird house in this area!
And lots of swiftlets were visiting at the first day I turned on the amplifiers!
Many thanks to 30 workers and my relatives who have worked hard for 6 months to make my dream (half of my dream) came true! This was my biggest investment so far after the investment on my children!
Here is my true story: One local contractor threaten me before that without his works, my BH won't have a single bird! ... The other promised that if I used him my BH would have birds in the next day! Otherwise, my BH will be empty!... He will walk by his knees, or he will give up his career if I could do it myself! He swore! and even worst, they asked some neighbors to close all entrances so I couldn't construct my BH in my properties! The chosen contractor have done 3/5 works and took all construction, consultant money included money from his workers then ran away. He abandoned his workers. I didn't think that you had ever faced the worst case scenarios as I had. No problem! I determined that I would take over and do it from A-Z myself with all costs! and I did successfully!
Ironically, these so-called Sifu built BHs in my neighborhood and their BHs had no nest for years! Their BHs are failed BHs! They are struggling to meet the basics of Swiftlet Farming!!! Of course, those Sifu asked my workers what have I been done? what were "the secret ingredients"? Honestly, I told my workers that I had the "Dragon Scroll" and I am able to defeat any outlawed Sifu!
Lesson learned you must be swiftlet farming master: do BH by yourself and hire workers, constructor and pay them by day basic.
Those swiftlets are visiting new BH in the morning
