Today April 15 2013 I was invited by some scientist from a Local Agricultural University to look at a BH that the owner have surrendered to those owls.
Started at about 10:00 am and reached the BH at about 11:00am.
It was a one story building about 30 feet X 45 feet and about 20 feet high.
The BH was in fact build on an abandoned fish farm cement pool.
The owner initially thought that it was a much easier investment as compared to rearing fresh water fish so he opt for swiftlet farming.
After a number of must with some success the BH was infiltrated with those common owls that uses his BH as a play ground.
The owl shits and those animals balls were found and many places.
The white colored shit were common on many part of the building.
His way out was to stop the sound and find a way to catch the owl. Until this moment he could not find one.
After the inspection works I told him about his bh health conditions.
A bit on high temperature and too bright.
The owl issue can be easily solved but the heat inside his BH was not good.
The inner walls were above 33*C and the air inside was above 30*C.
He confessed that he used two layers of cement boards with a 2 inches thick styrofoam sandwiched it between.
It was not the right thing to do and the only way to cut down the temperature is to prevent direct sunlight onto those walls.
That can be done easily too but my next big problem will the heat from the ceiling.
Hmm... this is one common mistake by many newbies who think they know better than others.
If he should engaged a knowledgeable Sifu I think he will not be in this tight situation.
My only task now is to submit my full report to the Scientist and I would say that this is not a very simple job.
