Farmers mostly sell to collectors/middleman. Nowadays some even come to harvest for you. Some come all the way from Indon to sapu nests. Collectors then sell to process factories/exporters. It's not that simple as you think to process bird nest. Without skill and experience you might end up lost money.i.e. Your processed nest damaged become lower quality class price lower than the raw nest you bought in. Even some operationg factory don't have the skill to process cup shape nest. Only process nest strands and broken pieces nests.

Hi seeseng, im new here. You contribution to the forum have been great. Im a swiftlet farmer myself, just want to let you know about my own experience. Not all air-conditioner installation are successful due to the smell emitted from the freon gas. Some swiftlets are very sensitive to this smell and would fly away rather than staying in the farm. Some farmers are actually spending the money to build concrete ceiling below the roof. This is of course costly. Thus, some are resorting to some methods that you were suggesting earlier, i.e. water sprinkler on roof, insulation, turbine ventilation (quiet mode type).
