To my mind, this data confirms one thing – that EBN farming is very lucrative. So lucrative that many entrepreneurs plunge into the business with very little knowledge about the technology involved. In Indonesia and Malaysia, the number of nest farms has expanded faster than the bird population. But even in Indonesia where the technology was developed, the failure rate remains high.
Early in 2006, unfazed by this knowledge, I build my first two nest farm structures in Southern Mindanao applying technology learned from Indonesia and Malaysia. The structures, excluding the cost of real estate, costs between P250-P300 thousand each. My design proved effective, at least insofar as maintaining the internal temperature lower than the outside temperature without the use of any equipment.

My site selection was based on two criteria: First, from observation I believed that these areas were swift habitats and, second, I would not spend for the cost of the real estate.
It took 18 months before I saw my first nest and in only one farm – in November 2007. No attracting technology was used. No sounds, aroma, etc. Today, December 2008, more than twelve months after, this farm has 20 nests. The other farm remains empty. The nests, by the way, are esculenta or grass, nests.
A successful farm should produce nests of sufficient quantity to recover the investment within a reasonable period of time, say, three to five years. Therefore, to recover my cost I need to produce 1.25 kilos of white nest per year within five years, and since I only have 20 grass nests (although the colony increase should be geometric, not linear) I would be a doddering, geriatric case before I harvest my first kilo of white nests! It was time to shift strategy.
